What's your overall opinion of this trend (https://www.reddit.com/r/TrueFilm/comments/xpgjwf/why_is_there_a_lack_of_sincerity_in_modern_films/) or arc? For example, the Full House, premiered in 1987 and was ultra sincere (https://nypost.com/2009/02/06/parenting-sitcom-style-saget-is-much-better-at-wry-then-ham/).

About two years later, came the decidedly cynical (https://www.cbr.com/seinfeld-relevant-cynical-netflix/) Seinfeld. Arrested Development come the mid-2000s, was probably the peak of the post-Seinfeld cynical (https://ngplusblog.wordpress.com/2013/05/29/arrested-development-season-4-a-cynical-charm/) sitcom arc. There was also, It's Always Sunny in Philadelphia, which is darker (https://screenrant.com/its-always-sunny-iasip-darkest-episodes/) and more cynical (https://collider.com/most-cynical-tv-comedies-reddit/) than anything else though.

Sincerity in sitcoms (https://www.nytimes.com/2021/07/26/arts/television/ted-lasso-the-office.html) probably didn't become really popular (https://virginiapolitics.org/online/2019/10/21/the-good-place-david-foster-wallace-and-the-politics-of-new-sincerity) again until The Office and Parks & Recreation (https://content.time.com/time/magazine/article/0,9171,2058210,00.html).
