I think this movie had the best plot of the entire franchise (edit: Actually, after careful thinking, it fits perfectly with the cannon!)
also, both Yamacha and Krillin got to do something other than shout, which is nice (I think this was yamacha's best fight since the sayian's arc), a lot of cameos (Kai, supreme kai, elder Kai, the ape from heaven) and everybody acting as they should be.
Goku and Vegita were amazing in this one, and the revelation about the robot thing took me by complete surprise.
And thus ends the tale of a sad villains evil reign simply because he appeared too late in the time line
