Visually, close to being the most imaginative film I've seen. The scape of it is much bigger than I anticipated, probably too big for its own good. However, for something as uncharted as travelling to another dimension to save humanity, you'd expect to build some sort of empathy.... you don't, despite it relaying the father/daughter relationship back and forth + it's parochial in that it only focuses on a small part of a small town. Besides the protagonist (well, even he isn't excluded from this), all the characters are without substance, and with that their actions sometimes don't make much sense and don't fit too well with the exposition. Gender roles are too played on as well. Dialogue isn't great, far too much surface small talk and the humor is used at the wrong time and too often. By what you think is the third act coming to a closure, it goes on, it could have ended about three times and unfortunately it ends on the wrong note. Especially how it's most captivating trait is to make you 'wonder', and instead of ending with that theme (which it very well could have), it tries desperately to wrap things up and delivers something which isn't palatable - the suspension of disbelief is flipped 180. Acting is great, even I didn't mind the stunt casting. I don't know too much about astrophysics, but that 'fifth dimension' take was pulled off too perfection. You need a second viewing to digest everything though.
Watching it in IMAX 70mm is a must.
