Pretty much. But There is indeed a case to be made for movie theaters because we are social beings. I have a fancy espresso machine at home but I still stop by a coffee house every once in a while because of this social aspect.
So when it comes to movie theaters they can be a plus but they have to know their place and care about their audience. We have one theater I like which is in the more upscale area where people are also more educated and polite. They have big comfy seats with huge arm supports which make everyone sit far away from their neighbor, reducing chatter. The rooms are small and big seats eat into it even further, again reducing chatter. They police cell phones well. They are clean and they are punctual about taking about 10 minutes for previews so I can go in late and be sure to just see the movie.
If I want social interaction with friends I will watch at home. But then someone will get up to pee, someone will take a call etc. If I want social but polite and fully focused on the movie then I will go to the movie theater (but you have to know which one is good for this purpose because most can diaf, not literally).
