This movie is a different version of 1st Dragon Ball saga (1-13 episodes). It retells the events pretty much differently, there are different enemies, and much sped up pace. I think this movie possibly ruins the original anime story which is really good, but story in this movie is pretty bad... The only good thing about this movie is the ending, little girl's wish and miracle coming true, the ending moment was pretty strong.
This movie is for those who want to see a different version of first dragon ball saga, but beware...
