I really want to see this. Partly because JGL seems like a cool dude, and also because I've heard it compared to a lot of great recent action movies like Drive, Inception and Children of Men, and much of the critical buzz has been positive. Also, word is that Rian Johnson got some time travel logistics help from Shane Carruth, of Primer fame. I don't know much about it beyond the premise, and I'm looking to avoid being too spoiled like I was for Inception.

Yeah, that's basically the main reason I'm convinced it won't be stupid about the obvious paradoxes in the premise.
