I can't explain it, but there is a pattern of superhero comic books' live adaptations doing better than their anime counterparts. I know most folks are not open to the anime live adaptations due to the recent flops with Dragon Ball Evolution and Avatar (technically not an anime).
You're pretty optimistic. I do hope they do a good job. 17 and 18 look great by the way.
I checked it out. A improvement over evolution but there were some questionable casting calls in there. 17 and Trunks just don't sound or look right. They don't have the feeling you get from the characters behind them. The rest are pretty good for what they have to work with.
