Edit: I did it! I mean, I didn't watch as many movies as everyone else. And I didn't write reviews for any of them. But I will take my small accomplishment.

I will never watch 31 horror movies in one month. Or 31 horror movies in 47 days. Or 20 horror movies in 47 days. But I am willing to try that last one!

Here's my go at this, for the first (and probably only) time. I am limiting myself to films I have not seen, as there are many that can be described thusly. And I'll start on September 15.
