Most intriguing about this movie is its commentary on religion---questioning the rationality of faith in the modern age---and commenting on the use of faith as justification to commit horrific acts. Each of the movies characters is incredibly complex and each of their viewpoints leads the viewer to question the themes of the film even further. The trouble is, all of these wonderful things happen in the first half of the movie, before things get "scary." For a "suspense/thriller," this is a pretty long set up. When the "scary" part begins, it is legitimately scary. The questions raised in the first half of the movie as to whether the girl is actually possessed actually add to the suspense, as the audience is forced to question what they have been told and what they might have believed. The movie maintains an heir of suspense (this doesn't mean that it is traditionally "scary," but that we are left suspended--not knowing what might happen) for a good part of it's second half. With each reveal, the viewer discovers that, once again, they really do not know what is going on. The problem is, when you do find out what is going on in the last five minutes of the film, it is so ridiculous that you'll wish you'd left before you found out. But other than that, this is a very solid, often interesting, movie. Those who go expecting a "scary" move will be disappointed, no doubt.
I will admit, I was immediately won over by the, sadly short, cameo by Richard Dreyfuss. It's not a masterpiece...but it's not intended to be. It's graphic, gory, and often very naked--- three elements which may not add up to the perfect movie...but do add up to some great, and very entertaining, entertainment, The cast is strong, the 3D lot's of fun, there's a delightful appearance by Christopher Lloyd, and the script is sturdy enough to sustain its 90 minute run time. What more does one need out a fun, summer movie romp?
