Interesting topic. Generally speaking, I'm probably of the "I'd rather watch it at home" category. That said, there is still something that the theatre offers that you just can't get at home. I'm not even sure I can put my finger on it, to be honest, but I'll try. For one, my kids (12, 11, and 8) mostly still enjoy going to the movies. I say "mostly" because my "12 going on 16YO" daughter is probably a tougher sell these days than the other two. We probably go, as a family, a handful of times per year. And, usually, we go to see a movie that they're wanting to see... The latest Marvel movie, Guardians of the Galaxy, etc. That said, I did take them to The Covenant a month or two ago (which was totally my choice, not theirs), and they actually enjoyed it quite a bit.
Side note.... A few months into Covid, Costco where we live started selling two-pack Cinemark/Century movie tickets for $5.99. At the time, given that regular-priced tickets are $12-15, I was initially pretty skeptical, wondering what the catch was (not to mention wondering if movie theaters were going to survive the pandemic at all, given that everything was shut down, lots of businesses closing permanently, etc.). I inquired as to whether there was any catch or fine print, and the Costco employee I spoke to basically said that there was no risk. If the theatres go out of business permanently, she said I could always return the tickets. So, I bought a bunch (I think there was a limit of like 20 at the time).
Long story short, over the course of a few months (and until they stopped selling them), I bought 20 or so movie tickets every time I went to Costco. Probably a couple hundred in total. All for $3 each. I'm a bit of a gambler, I suppose, and I just figured the potential reward outweighed whatever risk there might be.
So, for the past couple of years or so (since the theatres opened back up), we've been using the pre-paid tickets, which definitely makes it easier to justify going. If not for those, I think I'd be a bit more reluctant to take the whole clan to the movies, which at regular price, would cost somewhere in the range $60-75 (just for the tickets, pre-concessions).
All of that said, personally, I think I just enjoy the nostalgia of occasionally going to the movies. I'm a bit of a loner (and a single dad, in a blended family with my three kids every other week), and if I wasn't so busy with work, coaching baseball, and other things, I could see myself going to a matinee by myself every week or two, like I did when I was younger. THAT said, I do find it harder these days to find movies in the theatre that I really want to see. Seems like everything is Sci-Fi, Super Hero, or Horror, none of which are my genre of choice. And, I really don't enjoy going to super crowded movies, so if I've got any choice in the matter, I'm going when the place is half-full at most.
Lastly, I'm a sucker for really good buttered popcorn, and no place makes it better than at the movies, so I think of that as an added bonus. Once I run out of these cheap tickets, though, I may strongly consider buying the popcorn "to go" and watch the movie at home.
