The nods to other movies was fun. Pulp Fiction, 12 Monkeys, Toy Story, the Black Mirror episode where they bring the wife back but she starts spewing advertisements, etc. The real problem I have is that the main character is trying to "save the world", but he's obviously INSIDE a program. It's not quite Inception, not quite The Matrix. The feeling I got from it was that we're watching a computer program play out; basically someone wrote a program where the characters all believe they are real, but there is no "Real" world. Thus, Sam's character is in an endless loop for the pleasure of whoever wrote the program. He "remembers" growing up with his mother in the bunker, but that was all inside the program, too, evidenced by all the wacky, obviously fictitious shit like navy seals, rats, a giant Akira-style cat, etc.
The bottom line being: since there was never a "Real" world to save since absolutely no part of the story existed in the real world, it ended up being meh. That being said, if the characters were "sentient" and every "loop" was some kind of real world he was leaving behind every time he pushed the button, that would be kind of horrifying. When he zaps out at the end, the "program" didn't end and reset. It kept going with those characters living with the outcome.
