Gattaca - one of the best speculative sci-fi movies ever made. Also, just a very inspiring film about fighting for your place in the world.
I also agree on Speed Racer, I've only seen it once, but loved the experience at the cinema, I don't know how much of that will be lost on the small screen though. But, even apart from the blindingly brilliant psychotroprix visuals of the races , it was a very fun movie, and possibly the only live action film that has successfully adapted the feeling of a cartoon from the source. The Wachowski's brought something new to the screen here, Scooby-doo, the Flintstones, Rocky and Bullwinkle etc, they all felt like the usual live action thing, just an amped up pantomime for kids with sfx, no real attempts at innovation by bringing something new to film in the transfer. I ain't seen anything onscreen before like those fights at the end with Racer X, all those crazy swirly lines etc, awesome. Really need to see it again to recall more details, but I definitely left the cinema feeling like I'd seen something I'd never experienced before, which does not happen often, just like when I saw the Matrix.
