I need to preface this with two personal facts:
- I LOVE Jake Gyllenhall movies. Always have, ever since Donnie Darko, and yes, including Prince of Persia.
- The only movies I love more are Sci-Fi movies, in particular ones that make you think.
Luckily, Source Code fits both these categories. Originally, when I first saw the trailer, I thought it was going to be very much like Deja Vu without Val Kilmer, and it is, to a degree. It's a very similar style of movie: The protagonist is thrown into a situation with ludicroulsy advanced technology, and risks everything to save a girl, but that's where the similarities end.
