Predictable, uninspiring Story (copied from Enen no Shouboutai?).
The characters were boring and one-dimensional. Seriously, I've seen better character development in 23 Minute Episodes than in this 2 hour Movie. The Hero was just a copy/paste of Kamina while lacking his background. The villain was just a cartoonishly bad.
Fight scenes where they just stand and shout each others names while the camera does 360 backflips. The pink/neon colours are cool during the first scene but get boring quickly and don't look like a threat at all. Basically it's an action movie about fire where it's hard to follow the action and the fire looks just silly.
The Animation (Hiroyuki Imaishi) and OST (Hiroyuki Sawano) are the only good things about this movie. As a fan of TRIGGERs past works this really is a big dissapointment for me.
