The biggest problem I see for the involvement of Spike (and Angel) is that they're immortal vampires and supposed to be eternally young. If they are included in the reboot in some capacity, they'd have to find a way to explain how both characters have visibly aged over the last 20-plus years. Or they'd have to use some shockingly great de-aging effects.

The redesign saved the movie, and it would not have become a franchise. Looking at Ugly Sonic, you could tell the studio's thought process was, "We need to make Sonic look realistic, like an actual hedgehog. And he needs to have really muscular legs like an Olympic sprinter because that's realistic." Meanwhile, they ignored that they introduce Sonic in the film as an alien from another world, and therefore he does not need to be realistic at all. And their attempts to make him realistic ended up making the character look distractingly bizarre, grotesque, and not visually endearing to the audience.

Honestly, though Jim is fantastic as both characters and taps into that manic comedy of his 90's films, I could see a Sonic 3 in which Jim didn't return and Gerald Robotnik was played by a different actor as the movie's central villain. Granted, it would be obvious that they needed to replace Jim, but Gerald was already established in the games, so supplanting Ivo with Gerald wouldn't feel too jarring.

Maybe they're building toward their own version of the Four Supermen from the comics? They have Steel, and either Jordan or Jonathan could be Superboy. I wonder if we'll get Cyborg Superman and Eradicator as well...

If Vader's helmet shielded him from a Jedi using the Force on his mind, then how was he able to communicate to Luke through the Force at the end of Empire Strikes Back? How is Luke able to use the Force to sense Vader's internal conflict in Return Of The Jedi? Surely, his helmet would've acted as a wall to prevent Luke from being able to hear his father's thoughts and feel his emotions.
