$50 is a bit high. If it were in the $25 - $40 dollar range I'd do it for the 2 or 3 movies a year I really want to see when they are in theaters. The closest movie theater is about a 25 minute drive now. You have to drive there, it's always crowded, wait in line to buy a ticket, potentially way overpay for concessions, try and find a good seat, deal with idiots who won't shut up during the movie then get back to the car and spend another 25 minutes driving back home. As a result I've seen one movie in the theater this year.
There used to be a movie theater in the town where I both live and work. It was right next to my old office building. I used to go to movies all the time because it was so convienent. Prices were dirt cheap during the week before 5 PM. I could go over on my lunch break, get a great seat, catch a cheap flick, leave after an hour when the lunch break was over then go back the next day but time it so I'd pick back up where I left off. I could do that for $10 total if the movie was under two hours in length.
I'd definitely pay $40 for a movie I really want to see if I could watch it at home. No drive, no crowds, no wait, good seats, cheap snacks if I'm hungry and no drive home afterward.
