I mean there was a time when Iron Man and Batman were considered childrens genres and adults who would collect batman comics were seen as man childs. But now most of the audience for the marvel movies are adults and its treated as as more of a serious genre with adult themes and complex plots. Could DBZ ever be replicate marvels formula and be successful, catering to a more mature crowd than the usual 10-25 year old weaboos.
Wouldnt mind seeing a CGI spirit bomb and supersayian transformation on imax too.

i would much rather have the japanese do it actually. I think most would agree. And theres a large and dedicated fan base in Japan. I prefer it actually when i think about it. English subs will be all i need.
