Oh man, I love Movie 10, but Movie 11 holds a small place in my heart because it was my first fansub ever. It's not really good in terms of plot, but I echo what everyone else is saying: They used really under-appreciated characters.
Actually, there is one part of Movie 11 that I really REALLY like, and that is Dragon Power and the ending credits in general. It actually gives us insight to Goten and Trunks growing up together.
Man, What I would give for an OVA based off the adventures of young Goten and Trunks pre-Buu saga.
Ohhh...I just got goosebumps.
