Ideas were there, movie making skills were not

Near the end of this movie, it features some pretty interesting plot twists and scenery, suggesting that some creative minds were involved. But it contrasts starkly with the rest of the film, which feels very artificial and poorly made, like a cheap TV movie.

A loud movie about a world and people that only exist in movies

I probably should write something like "A daring expose of the decadence and ruthlessness of the inner workings of Hollywood", but frankly I found this a rather loud, unpleasantly over the top movie, with unlikable, unrelatable and exaggerated characters. Pretentious and Oscar hungry.

Boring, messy, silly and not scary

I was already getting bored with exorcism movies, and this is one certainly isn't turning the tables. The only novelty is that there are two victims at once, and three people doing different kinds of exorcisms at once, which turns into a mess, looks ridiculous and none of it seems to do anything.

A thrillride

All in all a really satisfying movie that draws you in by feeding you small chunks of the puzzle without overdoing or spoiling it. Interesting characters, interesting and well paced story.

Perhaps if it had decent stories

The stories consist of computer graphics alternated with (amateur?) actors doing stuff, with no real sense of connection. It's all quite hopeless, even if if the clumsiness of it all almost makes it sympathetic. The truly unforgivable sins were the supervague stories and random sensationalist title.
