I actually watched the first movie by myself in the dead of night with no one home and the door open the whole time (possibly have told this story before in other threads). Really an incredible experience lol. Later found out my friend had done the exact same thing and had the exact same experience! Sadly as I've said before too...the subsequent films have not had this affect on me as the first one has for whatever reason.
The theatre experience was not as great as the DVD watching experience. The theatre experience I had reminded me of the audience that saw "The Blair Witch" project...sigh. Too many teenagers talking and making fun of the movie, which of course made the adults yell to them to shut up!!! LOL
