I've really started to despise going to the theater to watch a movie. The whole experience is starting to get to me. From the overpriced tickets and snacks, to the obliviously rude moviegoers. It's just no more fun.
As for the PQ, I agree that home theaters, even my 51" Samsung, have a better picture. I feel that a trip to the movies now is only to watch a newer movie on a larger screen. But lets face it, if all we wanted to do was watch the newest movies, we could easily "acquire" them for home viewing.
I think I've grown out of going to the movies. Simply because when I was younger I wasn't aware of the costs, rude people, and mediocre picture and sound quality. Now though, I can have a dinner date, go to the lakeside park, and go home to watch my newly purchased Blu-ray. All around, a better experience for the same cost as a date to the movies.
I admit though, I don't have kids yet. I can see how this would change things up.
