I have a long history of dropping shows after several seasons, often for benign reasons like i got busy, lost interest or just moved on to something else. a lot fo times once the show moved onto the the trope marriages, kids/pregnancy arcs I move on because it's often a wash rinse and repeat script wise across the shows.

Sons of anarchy, never got around to the final season.

walking dead once they got pushed out of the prison (forget the season) never picked it back up.

Final season of Super store and B 99 were unwatchable and dropped it. The Office is very hit or miss post Michael and I hate the nellie character so its hard to watch.

Master of none had a great 1st season, second season was a little more of a chore to watch and third was straight garbage and dropped it part way through.

Watched second season of Upload, have zero interest in keeping up with it, same for The boys, season one, no interest in anything further.

Took me several years to finish community, the final season and a half or so i always lost steam and gave up.

Dropped Shameless when it just became hat social issue of the week can we plug very superficially. same can be said for OITNB, solid freshman season, jumped the shark after.

Lost, forget what season i stopped watching because I lost interest. Same with The americans, simpsons is sporadic but not kept up on.

ITASIP, Rick and morty, Bob's burgers have gone from must watch to whenever i get around to it.

the list can go on, but overall it's a bit on the rare side if i can keep the momentum through an entire series.
