Too much gore, too much death... that's good for teenager.
Action... of course but there are no need to Kill a human every seconds (they could make a closer cast for Requiem with fewer people and make their character more interesting with death which shocked cos you don't expect it.)
Brother Strause are just bad director, they can claim "yes but you know when you make a movie... the production..." it's just not a reason at all, it explain a part of what happened but if you don't stay the master on the set of course you gonna make shit.
And about color correction, they can't say that's a problem with the producer, it would take less time to don't touch color than they did it.
But i still believe in the movie, the main problem is how the Camera was use. (of course, i don't take in consideration the script, etc. which are total bullshit.)
