Okay, i just saw it off a Link Carmi provided.
It was about 1 hr and 18 mins long.
If you ask me, I thought it was okay. Sort of like a spiderman 1, going into depth with the story of Goku and not a ton of action.
However, if i had to speak for the masses, I would say that no one would truly like it.
I am looking forward to the next movie, just b/c they will probably have Goku as a Super Saiyan and so forth, but if it is not good, I don't plan on seeing the 3rd.
I say, if you got an hour to spare, why not?
