These days I can watch high quality films online within days of their release. Does anyone even bother with the cinema anymore?
I prefer DVDs, but it really depends on the size of your screen, and the set up of your home theatre system.
If you've got a big enough screen, and the right speaker set up, you can re-create the theatre experience minus the noisy kids, messy floors, uncomfortable chairs, and imbeciles who kick the back of your seat. Plus you can enjoy whatever food or drink you want while watching the movie, ...are free to go pee whenever you want without worrying about missing something, ...and you won't have to turn your cell phone off.
A big challenge with not going to the theatre tho, is by the time the film comes out on DVD, it's hard to keep yourself innoculated against spoilers.
