I went into the theatre to see this movie expecting nothing more than to enjoy watching Channing Tatum skate around as a beautiful space elf. With such low expectations I was absolutely blown away by how much I loved the movie; well, the world of the movie. I was absorbed by how many legends, myths, tales, etc were referred to and explained in this film, such as aliens we typically refer to as "Greys" and why witnesses are always fuzzy on the details. Crop circle, vampires, alien abduction, and more are explained while building up an expansive universe that may not actually make sense (why, exactly, do all these other races bow down to weak humanity?), but is at least entertaining.
Upon my second viewing I realized something I hadn't noticed in the theatre: the dialogue is almost entirely exposition. There is so much to say in order to build this version of reality and so little time to say it in that apparently the directors decided the best way to do it would be to literally TELL the audience. I felt like Channing Tatum was reading the Jupiter Ascending wikipedia for a good part of the movie.
When I got this version of the film I watched it in 3D, which was alright. I'm no expert in 3D but I can say just from experience that this one felt a little more...headache inducing...than, say, The Avengers did when I watched it with the same setup. I imagine anyone who would want the 3D version knows what to expect by now.
While this is not a perfect movie by any means, I still feel the need to give it a good rating because it does what film does best: entertain. I was glued to my seat, mouth agape the entire time I was in the theatre. Give it a chance, enjoy the ride, and don't think about it too much. It's exactly what it should be.
