jake gyllenhaal is good in action movies, in thrillers, in dramas...
he's good on everything.
i liked this movie, it was really entertaining and interesting, it can work as a sci-fi movie and as a mystery, it also had some great concepts and a great premise overall, the soundtrack was a bit annoying tho, and it had some cliches, but overall i recommend it.
