This film was the most hyped Dragonball film in a long time mainly because Frieza returns. Also there is a new Dragonball series running adding to the whole atmosphere and excitement of Dragonball but this film severely disappointed me. I have been a Dragonball fan for like over 10 years.
The main problem with this film is that it feels like a copy/paste job of every other film. Ever. If you have watched any other Dragonball film you can predict the results and the steps that happen to reach the ending. This goes for the plot and story progression so that you could write it yourself. Frieza returns, supporting cast fumble around until the big fish (Goku/Vegeta) show up and they fight with very expected results. And without spoiling anything the film is resolved using a plot mechanic that was literally used previously in films and the series.
And frankly the whole Super Saiyan God/Super Saiyan God Super Saiyan forms (red and blue respectfully) are nothing more than desperate palette swaps to keep up the idea of power progression that is such a worn out element even starting in the original Dragonball. The design of these forms are just... lazy. As for Frieza's new design, it's also just another palette swap.
Another poor issue is the canon of Dragonball by now. Super Saiyan was always implied to be so damn strong and just having a SS fighting on a planet leads to severe damage to it. But now these apparently insanely god like being are fighting and it has the same effect on the surroundings as fights in early DBZ. It's just wrong.
On the good side it's the best looking graphically speaking though I have seen way more awesome scenes in the main series. The sound is on point and features a kick-ass song from Maximum the Hormone.
I give it 3/10. As a hardcore DB fan who has literally watched everything DB related by now... there is no real reason to ever watch this. It brings absolutely nothing new to the table. You will get more enjoyment writing your own fanfic or re-watching older films.
