CHEATING!!!! And not a fair way to actually judge a movie. However, it DOES work to help decide if you want to really take the time with it in the first place -- and I just did the same thing myself today with a non-FLM torrent download that got quickly deleted! I am with you in that deciding "Not For Me" is generally pretty easy, once we are set in our ways enough to know what we like.
I think we both qualify for that.
