When you factor in being able to have cheaper food, not to mention intermissions whenever you want (bathroom break, making popcorn, etc), I feel like streaming is still better than theater, price-wise, even at $30/movie.
Unfortunately, it doesn't _feel_ that way. We still haven't seen Mulan yet, though, and I'm not sure if price is a factor in that. I suspect it's a small factor -- we subscribed to Disney+ to see Hamilton, for example -- but it just hasn't come up in months. I forgot about it until writing this comment.
It's hard to convince myself that I should pay $20 or $30 for a screening, when a year from now I can likely rent it on Prime for $10 or less.
