Watching films at home comes nowhere near the experience of seeing them on a big screen, with proper, loud surround sound. If you turned up your TV volume to cinema levels you'd get an Asbo on the spot, but films are made to sound good at auditorium levels and to look right on huge screens.
I went to see Nacho Libre at the Gate Cinema in Notting Hill. Bought a glass of wine at the bar and took it in - there are tables so you don't spill your drink. AfterwarRAB, the staff asked me what I thought of it (not a lot). That's what a proper cinema should be like, a friendly, comfortable place to relax, not a soulless hangar on the M62.
