Dude, I'm being turned off going to the movies too. Last one I saw was ironman 2. Craploads of ads, followed by loads of previews, and people behind me coughing and sneezing and carrying on with their colds. Loved the movie, but I think I'd enjoy it a helluva lot more at home because since then I've gotten blu-ray and 5.1 sound to go with my 46" tv. I'd get a better experience at home now.
For less than the price of just two tickets, I can buy the blu-ray of the movie and fully enjoy that instead of having to put up with rude people. Hear that cinemas? Too much pre-screening crap and lack of ushers is loosing you to home theatres.
