I guess because I was isolated from the full experience of focusing on the film, I was able to pay attention to the actual dialogue, and it sounded so... overdone I think is the good word. Just like, nobody talks like that. People are speaking in the movie like they're reciting prepared speeches on destiny and junk, it really bugged my senses.
The plot jumped around way too much for my taste, sometimes it followed the time traveler, sometimes his wife, sometimes neither, back and forth through time in every direction. I'm not afraid of a complex plot, but when it's scrambled that badly, I can't take it.
As for the story itself, I couldn't get emotionally invested, because there didn't seem to be any danger or unpredictability. The traveler knew exactly what his past, present, future, and demise would be like. He even got to know his daughter after his own death. Without any actual danger, the drama seemed to fall kind of flat. I might be spoiled though by other, better fiction though.
So that's what I thought, but I wanted to get opinions, maybe I'm crazy and it's an incredible movie, or maybe I'm fully justified. idk, but thanks for the responses so far.
