As good as the book?

This book ROCKED... Completely creepy, claustrophobic, and freaky. I have put off seeing this film, though, I gotta say. A brilliant horror novel often translates into crap once its adapted. Granted, the writer (who penned the incredible A SIMPLE PLAN, as well as its Oscar-winning screenplay that starred Billy Bob Thornton) also wrote THIS film adaptation. I dunno, the trailers look a bit lame. There arent too many decent thrillers out there, I still may check it out. Id tell you the plot, but then you'd think I was nuts to love the book...
