I don't get the hype for this film. It could have been so much more. The end was less about space travel, and more about unbelievable sci-fi. I like Sci-Fi's that are at least remotely believable. This movie becomes hard to follow at the end with all the sci-fi twists. The character development is fairly good, and for that I rated the movie slightly above average. However, with almost 3 hours, character development should be expected. The visual effects are pretty good, with the exception of the unbelievable near ending. I'm just not sure this movie was worth the 3 hours invested in watching it. If you're a McConaughey fan, you'll probably enjoy the movie. If you're not a fan, you could be disappointed.
