All 3D movies are the same. Seen one, seen ‘em all.
Now, don’t get me wrong - I like La Luna (the animated short at the beginning of Brave). However, I don’t necessarily think it was that much better than most of Pixar’s shorts. They’re often very sweet and emotional and I didn’t feel that La Luna was that much better. It was good though, definitely amongst their best, for sure. For me though, there is always Night & Day.
