The past decade of tv has spoiled people with quality TV shows.
Back in the old days of tv, we didn’t have story arcs. First seasons of shows were still rough. Networks often gave shows a lot longer of a lifeline to prove themselves. For example: Parks and Rec didn’t hit their stride into mid-Season 2.
For 90s shows, I recommend finding a Top 10 episodes list and seeing if you enjoy it.
This, there’s a LOT of shows before streaming services where I just beg people to skip the first season.
Always Sunny is definitely one that suffers from a lot of Early Installment Weirdness, it’s clear they had no idea what the hell they wanted the show to be at the start… Also Danny DeVito improves anything he touches.
Funny story, Season 1 was so bad the network said they would cancel them unless they could get an A-List Actor to guest star in an episode for a ratings’ boost, which went so well that said guest star wound up being a permanent mainstay.
