First of all, from the technical point of view, it's a disaster. Season 5 simply looks absurdly cheap. It's badly lit which is the main culprit for it's cheap look. Direction and editing are really boring, there is absolutely nothing imaginative about it (compare it to earlier seasons, direction and editing of first 3 seasons was really good for a comedy show and often supplemented the joke, now that's completely gone). Compositing is just bad and makes the rampant use of green screen very obvious (that one was a problem in season 4 too, but you'd think they would improve 5 years later).
Yeah, this was really bad.
The director for every episode for this season is a guy named Troy Miller. He directed the Dumb and Dumber prequel, a Michael Keaton kids movie called Jack Frost in the 90s, and a shit ton of standup specials. (To be fair, he also directed some quality comedy TV like Mr Show and The Ben Stiller Show).
In comparison to the first seasons, where we had the likes of Patty Jenkins, Anthony and Joe Russo, Greg Mottola, and Paul Feig among others behind the camera, this is a major step down that is reflected on screen.
