30-Day Horror Movie Challenge - Used to hate but now like...

Tagline: The only thing more terrifying than searching for the Devil... is finding him.

Synopsis: Dean Corso (Johnny Depp) specializes in tracking down rare and exotic volumes for collectors. Boris Balkan (Frank Langella) has recently acquired a seventeenth-century satanic text called The Nine Gates- a legendary book written by Satan himself. With The Nine Gates in his possession, Corso soon finds himself at the center of strange and violent goings-on. Not only is his apartment ransacked, it appears that he is being shadowed ferociously by others determined to regain the book. (Google)

I saw this in the theater when it first came out and I hated it. It was one of those "what the hell did I just watch?" moments. So, you might ask why I then watched it again when it came to cable premium channels. I don't know why, but I did...and I was hooked. Not sure if it was the book element, or the occult element, but I recognized it really was a smart film. Perhaps a bit convoluted, but the subject matter is actually really interesting to me. The critics don't seem to have liked it much...43 percent on Rotten Tomatoes...but it has an 88 percent liked rating with Google users, and 6.7 on IMDb, so really not universally hated. Needless to say, after that second viewing, it became a movie I would watch over and over again. It has actually been a while since my last watch, but I found out it's on STARZ so I think it's time for another rewatch.
