I have an LCD projector, so there's no need for me to go to the cinema.
It depends how long you are prepared to wait for a decent copy of the movie. Personally I actually quite enjoy going to the pictures, you cant get the screen and sound at home.
That's simply not true.
My house just doesnt have the room for one of those screens etc, and the cost of the professional stuff is out of my range, anyway. So for me, getting that setup isnt feasible, and anyway the pictures gets me out of the house.
I rarely go to the movies since I built my projector, although I do enjoy to go occasionally. The atmosphere of a movie theatre is very difficult to reproduce at home, the popcorn, the audience, etc... that's mainly what I enjoy about theatres now.
As for the original topic, I refuse to go kids movies these days. We went to see The Incredibles when it came out, and it was horrendous. We left after about 15 minutes.
