"If Zimmer can't extend beyond this comfort zone for a big-name title soon, then he is coming dangerously close to outliving his usefulness in the action/fantasy genre."

To the reviewer- I'm impressed, it sounds like you are a better film composer than Hans Zimmer. I'd like to hear what have you contributed to the action/fantasy genre lately?

"there are brilliant young composers working today who don't have hangups about large orchestras, who don't work in a chaotic scoring environment, who don't rely on the talents of other composers, and who have already proven themselves to be masters of handling major/minor key creativity and complex variations of theme."

There's no rule that that large orchestral sound, major/minor key usage, and thematic variation are the only effective ways to score. There's nothing wrong with those techniques, they work. Maybe you could be open to other possibilities (even if you don't think they work in this case). I think this review shows bias towards a particular style. Maybe everyone's cool with that. I'm just saying...
