I have literally never heard someone say this
>(besides the complaints you hear about prices)
Yup, there it is.
But also, to watch a movie in the cinema I often have to sit in uncomfortably off-center chairs. I can't adjust the volume if I think it's too loud, I can't pause the movie to take a piss and I have to listen to the troglodytes behind me eat popcorn with their mouths open. The movies start at rigidly defined times that may not be convenient for me, I'm not allowed to bring a pizza in, I can't do anything about it if someone has an inconsolable baby or kicks the back of my chair repeatedly and to top it all off there's half an hour of ads before the movie starts.
And yeah, I have to pay $15 for that.
All in all, cinema is still a very 1920's experience, and I don't really want that. I have a 3D home projector man, I got it second hand for like $200. It's not as good as the cinema projector, but I assure you my couch is nicer. I've just delayed my cinema schedule by 6 months. Spiderman: Homecoming is being released soon, I'm pumped. No spoilers please.
