It was fun, but pretty forgettable. It drags a bit at the beginning until the guy shows up. Rapunzel's a cute kid 'n all (She's 18? HA HA HA! That's a good one! Oh...you were serious...), but I didn't find her all that interesting. Neither was Ryder (i.e. 'the guy') to be honest, but at least he was fun and fun shit went down whenever he was on screen.
The horse had excellent comic timing, which is something you can't say all that often.
It was pretty odd seeing Disney's first CG 'princess' movie though, complete with a whole slew of completely forgettable musical numbers. The old woman had a nice set of pipes on her though.
Oh and the chameleon was cute.
