If I really enjoy it, I can watch it over and over. I've watched Hot Fuzz several bajillion times - watch it until I passed out every night for WAY too long. If that counts as watching it, anyway, haha.
But also, if I really enjoy certain parts of a movie or television show, or what have you, I can watch it over, and over, and over, if I watch it with someone else who hasn't seen it yet. I get almost as much satisfaction gauging other people's reactions to things that I enjoy, as I do seeing them myself.
Seriously, I watched Avatar (in 3D, because god it was boring without it), in theaters, somewhere around 11 times with different people; simply because I thought the action scene at the end was fricking amazing, and I had to share it with EVERYONE!
