The Last Exorcism (2010).
What a profoundly stupid little movie.
I could've written a perfect ending for this film. And to make matters worse... they totally set it up for it! In fact, I'm almost completely certain that many others could, have and/or will reach the same conclusions that I have.
Therefore, I propose the following experiment: For those who haven't yet seen this movie, please go into it with the thought that there's going to be some huge twist ending... and then try to figure out what it's going to be beforehand.
Now, having done so: Do you see what I mean? I'm sure I'm not the only one who sees it... am I?
Addendum: Whenever this film debuts on the pay movie channels (i.e. I don't have to buy it specifically - I'll just run a tape instead), I'm going to try to make a point of actually sitting down and typing up what I myself believe - and those who agree with my personal assessment regarding the same will likely concur - would've been a much better (and, in a perfect world, a proper/the "real") ending!
And here I was, all ready to log on and declare this to be my favorite exorcism film of all time... *sighs for what might have been*
