This movie delivers exactly what the title implies, gaming action. Butler fits the action hero role perfectly, and Michael Hall is a great fit for a evil genius.
That is pretty much the focus of this movie, I did not see a significant plot advance and watching Harry win and lose the same battles and make the same mistakes over again was not what I expected. You would think Harry being who he is would have grown into a formidable wizard by now; even if still young, no we are mostly back to book two in ability. I actually stretched to give up three stars, perhaps expectations were to high.
I am not a fan of prequels but this movie excelled. My wife who is not a trek fan really enjoyed the movie as well. Watch for some well known actors throughout the film.
