Every couple of years? But I do think the frequency of straight up comedies being produced is dwindling, and aren't popular enough to go to a movie theatre for.
For me, comedies are so much a matter of personal taste that I’m generally not interested in seeing them in the theater unless it’s with a group of friends or I feel like I have reasonable expectations that I will like the movie a lot. They’re not really like superhero or action movies where I can be pretty good at guessing whether I’ll like the film.
