I actually really enjoy 3D movies. It's the only reason I go to the movies nowadays. Otherwise I wait for a rental.
As for the 3DS, I love it but the 3D effect only works well for games where you don't have to move the device too much or switch between the 3D and non-3D screens too often. The angle of vision for the 3D effect is not very good just yet, so they'll probably fix that for future editions of the handheld, which I'm sure are coming in the near future. Either way, playing without 3D is just as fun. The graphics are as good as on the PSP, which is plenty for a handheld (until they wow us with the NGP?)
