I don't know why people saw this in theaters and supposedly were throwing up and leaving. The movie is not in the least scary, it is an over the top gore fest done in a slightly cheap manner. Some scenes were pretty well done realistically, but most were obviously fake and done poorly. The quality of acting mirrored the effects as most of it was bad, but a rare few scenes acted out pretty well.
Over all, from an average Joe, if you like gore fest movies this one will entertain, but don't expect to see a good, scary movie as this isn't it.
