You know about that saying "save the best for last?" It's in the case here. There have been good ones(12 and 6) and bad ones(11 and 7). But they're all nothing compared to this one. It has Goku, Vegeta, Gohan, Trunks, Goten, Videl, Bulma, Master Roshi/Kame Sen'nin, and Kuririn of the DBZ cast. It introduces Taipon, and the plot focuses on Trunks quite a bit. I can't say any more without spoiling anything, but it does have some good character development in some of the characters. Of course, the title is Dragonball Z, so of course you're going to see a huge, destructive battle during the second half of the movie, but I'm not spoiling anything! It's too good to reveal any important plot points!
BOTTOM LINE: This one's awesome!
