I had like the first 3 seasons of umbrella academy, but I felt really bad watching its final season 4 final I didn't like it at all, they should of ended it with season 3 and one episode in 4 it sucked that much up to the last episode, some reason the ending left me feeling cheap, I don't know any better word, that it sucked at the ending, killing off the Characters felt like a BBC thing, or I don't know even doctor who got to regenerate over and over again, but it felt short compared to other seasons, it's like did they shoot it during covid and waited until now to release it, or why did it have less episodes than all the seasons, I changed my rating on Netflix to one thump UP from Two because of its bad ending, I really think they could of somehow ended it with all the characters alive or some of them, and yes the children should of Bleeped out of Existence, since their parents were no longer in existence along with all the timelines that no longer existed, they really shouldn't be able to exist, plus they only jump to two of the timelines, and not all the timelines which existed, which is a little strange when you think about it, I guess, if I didn't like the first three seasons, I would of given the series a Thumbs down for its ending, it was just too brinish killing off all the main characters at the end of it. I didn't like it at all, plus the aliens really were not explained that much, and their childen the heros seemed like they never even knew their father was a alien, even when he talked to her or him about not being human like him, it went over his head it seemed, in that one season 4 episode, he started in season 1 as a her and I think it wasn't until season 3 that we learned that she was changed into a he, since she didn't or wasn't a he in season 1 to 2, and season 4 she/he had more of a man's voice than season 3 from what I recall, but that off topic sorry, my point is he didn't and the family didn't ever know they were raised by an alien from space.
