You're not wrong! I am open to dramedy as a (sub?)genre, and feel it has led to some phenomenal films. There are those tiny moments of human comedy in Manchester by the Sea which I think seriously enrich that film's humanity, for example. Martin McDonagh does a similar thing with his better films. But there is now a gap for something with solely comedic intentions like you say - a big one! I'm not sure how it was received but Bros was a small step back towards that, even if I didn't think it was that good of a film in and of itself. When it felt strange seeing a mainstream comedy actually advertised, it made clear that gap.

Cheers me up a little to remember that when I did go to see Jackass Forever, the screening was packed and I missed much of the dialogue to laughter. It was a great, great experience. So there is a want for it when it comes around!
