Saw Speed Racer the other day - and I'm rather impressed.
Oh, the physics are wrong, the materials science is bogus, and we won't even talk about the physiological aspects of the racing - but it was fun in a 'okay, we know this isn't a serious movie' way.
It's a cartoon. The colors are exceedingly vivid - the backgrounds at times seems almost drawn in. The characterization's close to what I recall the characters were like in the original series. And it's got plenty of 'edge of your seat' racing action.
(Of course, the next day we watched the Daytona 500. Funny how real-world racing seemed dull... they weren't even slamming into each other on purpose!)

So, one down on the 4 movies I'd like to see. The others are "Iron Man", "Prince Caspian", and "Indiana Jones". Any opinions on those?
