Another thread revived after months of slumber...
Tangled was a complete surprise, way better than I'd been expecting.
Mulan is a classic, and definitely one of the best.
None of the others stand out quite as much in my head. Lion King is okay, though when I watched it with some friends a while back, I realised that some people are crazy into that film. I'd seen it once, back when I was young, and just thought it was okay. My friends could sing all the damn words to every single song, which just made me confused at how recently they'd watched this kids movie.
