I just saw it a few nights ago and it was an angry leftist screed on par with something George Clooney would have produced. All the religious people are either hate-filled zealots or self-aggrandizing lunatics. Rather than making a case for Darwin's theory, the writer took a sledgehammer to religious people. Not very persuasive.
I can't recall where I saw it, but a recent expose was conducted about the writers of I.t.W, and the agenda they were grinding. Essentially, this movie, like so many others, were products of minds that gave rise to the red 'concern' (personally, I don't think nearly enough people were experiencing a 'scare').
