When you're a fan of the anime, you realize just how awful it was.
When you don't know the anime very well or are not a fan you typically enjoy it.
They advertised the show to be a live action version of Dragon Ball, which I was syked for until I actually started looking into the show.
There were hundreds of points I could discuss that were horrible, but I'll just tell you the biggest one.
Goku is the Main Character!
In the actual show he was a happy child who always saw the bright side of things. Nothing ever got to him and he was basically a hilarious and funny innocent kid that you got to watch beat the crap outta bad guys. Which equals epic awesome!
Though, in the movie he was a depressed angsty teen who had this whole horrible vibe about him. Which equals epic failure!
...how do movie makers go that far astray!?...
Clearly the writer was not a big DB fan...
