Everyone was praising this movie but honestly the ending was really bad for me. Maybe it's because I don't know much about that stuff about dimensions and other things mentioned. But honestly it really disappointed me. And in the whole movie there was too much physics so if you don't know it well you probaby wouldn't understand most of the things.

The other thing that was useless was the whole thing about love. It didn't fit well into the theme of the movie and it was unnecessary.
