Okay let me start with that I am a fan of the Manga not so much the Anime series, I understand that they will be bringing out a copy of the series without the fillers and pre fight power ups that I will love. Now that said.....Here it comes.
I went to see it and well if you like the story of Goku son and Piccolo then do not see this film. If you know nothing of Dragonball then this may actually be an enjoyable movie. You can look over the missing characters and almost absoulte killing of the plot to suit their own adaption which is awful. You may even be able to over look the fact of Goku's powers and the transformation at the end. Maybe even the fact that everything in this movie is almost an insult to the real deal. Thats of course if you have not read or seen the "real Dragon Ball" if you have do not see this movie and just trust me when I say it is like watching your childhood being torn down in front of you.
In Short just don't do it, thats 1 hour and so many mins I will not get back ...
