I decided to see if I could come up with a top ten as well. Considering I haven't seen or don't remember half of the films (admittedly mostly sequels and prequels, so eh) it was probably a lot easier than you guys had it. Mine went like this...

1. The Emperor's New Groove
2. Tangled
3. Frozen
4. Aladdin
5. Finding Nemo
6. The Lion King
7. Wreck-It Ralph
8. Atlantis: The Lost Empire
9. Wall-E
10. Up

Really, though, 2-6 could be shuffled around a lot depending on my mood, and the same for 8-10.

Interestingly, if I combine Disney & Dreamworks, a number of them would get shunted down.

1. The Emperor's New Groove
2. Megamind
3. Tangled
4. Frozen
5. Aladdin
6. Madagascar
7. Finding Nemo
8. The Lion King
9. Wreck-It Ralph
10. Monsters vs. Aliens / How to Train Your Dragon depending on my mood.

I dare say I am more likely to enjoy a Dreamworks film than a Disney film, but with so many Disney films they still tend to flood the list.
