Warning: SPOILERS for Avengers: Endgame

This week, the hottest topic of conversation that no one wants to ruin is MCU has outdone itself, capping off this chapter of its films, and changing the Avengers forever. 22 movies in and they still dazzle their fans.

While they are great at crowd-pleasing, though, Avengers movies aren't perfect, and neither is this one. No film is. Between whacky science and some other key decisions, the flick is a little more divisive than one might think.

Below this intro is an article filled with spoilers, so any fan not wanting to learn things they might not want to know, beware. This warning will only be given once. After all, to talk about logic flaws, we have to talk about all of Endgame, spoilers and everything. Read at your own peril.

Here are 25 Things That Don't Make Sense About Endgame.

Thanos Telling Nebula His Retirement Plans

Throughout Gamora and Nebula's saga of sisterhood, fans have learned that Thanos preferred his more aggressive, disloyal daughter. In the first Guardians film, she nearly destroys Gamora and all her friends just to try and please him. However, other than using her as a pawn, Thanos never really included poor Nebula, resulting in her eventually turning on him.

At the beginning of Endgame, the un-Dusted heroes are hunting down Thanos. They want the Infinity Gauntlet to change everything back. Nebula becomes pivotal here because she knows the farming planet that he always dreamed of retiring on. The only problem is that Thanos would never bother to tell Nebula anything that important to him. She might try to him or something.

Thor Letting Himself Go

The MCU excels in balancing out humor with serious, impressive action. During Endgame, though, they made a divisive choice that left a fair amount of fans unhappy. After failing to chop Thanos in half in Infinity War, Thor has apparently let himself go, as a King and as a human being. He has long hair again, a beer belly, and barely takes care of the remaining Asgardians. This transformation is framed as a sort of post-traumatic response, but compared to Tony Stark's panic attacks it's just not as effective. Furthermore, it's played off a bit too often for laughs. Thor deserved a better post-Thanos arc.

Captain Marvel Left Us Underwhelmed

At the end of Avengers: Infinity War, Nick Fury used a pager to Captain Marvel, an incredibly powerful woman who left the planet years ago. The end-credit scene framed her as a wildly important component to defeating Thanos, a person who would change the tide.

Unfortunately, though, that's not quite what happened. After all, the most important thing she did was play taxi for Tony and Nebula to get them back to Earth. Beyond that, she kind of just fades into the background. She's there, but exists as back-up, nothing more.

Considering many fans fell in love with her during her solo film, such a lukewarm and underwhelming role in Endgame becomes disappointing.

Valkyrie's Survival

Avengers: Infinity War begins with Thanos completely destroying the Asgardian refugee convoy. Without a home, the proud people are decimated and Thor remains the only survivor. Fans assumed that this implied all his kin, including fan-favorite Valkyrie, were gone.

However, the poster promotions for Endgame revealed otherwise: Valkyrie not only survived, but also wasn't dusted by the snap. Somehow, a small selection of Asgardians survived and now live on Earth.

While Valkyrie's survival is exciting, it doesn't make much sense. Their people only had a single ship that Thanos utterly wrecked. How did she and any others survive?  It doesn't make any sense and Endgame doesn't really offer any explanation.

Old Selves Meeting New Selves

Whenever a plot involves time travel, things get sticky. Star Trek and Doctor Who have been dabbling in the topic for decades with varying degrees of success. However, one of the key rules both series have cemented is that past selves should not interact with current ones. It's all about time paradoxes and how it affects a person's future, the works.

Well, Endgame completely disregarded that and had as many old versions of each character meet their new counterpart. Not only did both Captain America and Hulk have future-past chats, but Tony and Thor also had conversations with their now-ed on parents.

At three hours, sure the movie doesn't have much time for scientific explanations. But, really? The Department of Temporal Corrections is horrified.

Scott's Quantum Escape

When Thanos does his infamous snap, the post-credits scene of Ant-Man and The Wasp revealed that the entire Van Dyne family was completely dusted. Worse, this is while they are conducting Quantum experiments with Scott. After the five year time jump, Scott reappears, escaping the Quantum Realm all on his own.

Before this, the Pym science clearly expressed that without a ship or some sort of planned tether, it's impossible to return from the Quantum Realm. Scott seems to have disproved that. How? Who knows. Considering he's more an electrical and mechanical engineering dude, he doesn't have the qualifications to have solved such a conundrum. Though it doesn't make much sense, I guess fans are expected to accept he figured something out.

Having The Dusted Back In Action So Easily

All the people that were "dusted" by Thanos' snap were gone for five whole years. When the Avengers finally bring them back, they've been disintegrated and have lost so much time. While all of them have just dealt with this traumatic experience of literally falling apart, the movie forgets the logical refractory period for dealing with that. Their bodies might be completely out of whack. Instead, though, all of them jump back into immediate action, ing the fight against Thanos.

Sure, it's a sci-fi action move so the rules always get bent. But the catharsis of it all doesn't outweigh the absurdity all the time.

No Other Big Bads During Time Skip

In the entire 5 years after Thanos' snap, the Avengers don't talk at all about any other big bads attacking Earth. While it's made clear the average crime still happens, look at Clint's Ronin, no one has seen the new weakness of Earth as an opportunity. Considering how many galactic villains are in the Marvel universe, it's wild to think no one saw the chance and took it.

Sure, it would completely mess up the movie. When it comes to keeping the plot succinct and focused, it has its purpose. But from an evil standpoint? Absolutely at least one person would have taken advantage of the whole situation and done something.

Ronin

Ronin (not to be mistaken with GoTG's Ronan) is a dark persona taken on by several different people. In comics history, Clint Barton has held the mantle in his worst hours. However, the Clint that does that isn't quite the same one fans know in Avengers. The MCU Hawkeye bends some rules, but ultimately is a man who believes in doing the right thing and protecting his family and the world. That's why he ed SHIELD, after all.

While losing his family does pull out a darker, angrier side of Clint, the character we've seen thus far is more likely to back up with Black Widow than start on loner hunts as Ronin.

Thor Cutting Off Thanos' Head

After Nebula reveals Thanos' retirement spot, all of the Avengers get in a spaceship and head his way. When there, they discover Thanos' body was completely destroyed by using the Infinity Gauntlet twice. He put his life at risk to destroy the stones with a second snap, ensuring no one could reverse the damage he'd done.

Instead of letting anyone try to talk to Thanos or use him for information (or let Nebula get a cathartic stab in), Thor chops off the purple alien's head.

While it makes sense for Thor to feel guilty for not doing a better job taking down Thanos with his new axe, the reaction is a bit much.
