Breaking Bad. Amazing show but I just can't rewatch it.
Six Feet Under. It was such a good series... but soooo depressing...
The Shield. I can't handle the tension for a second time.
Six Feet Under and Big Little Lies. Amazing shows, but such heavy topics.
I can't rewatch the Lifetime show "Unreal". I enjoy every episode and can't wait for a new one to come out, but once I've finished an episode I can't go back. It's too stressful and somehow knowing what's coming actually makes it more stressful to watch.
I also have never been able to rewatch "The Wire"; it's too complex, and there's too much to take in for me. I plan on rewatching eventually since I suspect it's one of those shows that is better once you already know the general story because you can focus more on the fine details. But not any time soon.
Northern Exposure because it's not available for streaming, and I don't like DVD sets.
I had such a good experience watching Friday Night Lights a few years ago that I'm afraid a rewatch will taint it.
A lot of the more serious shows that were also iconic.
I'm not sure how long it will be until I can re-watch BrBa or Black Sails, which have been the biggest dramas that have ended recently, that I watched. I can watch a lot of comedies over again, like Scrubs, Seinfeld, PandR, and The Office, but dramas are still a bit tough.
Since some mentioned HIMYM, I could probably watch that over again despite knowing the ending. Same with Scrubs and PandR which had a story to go along with the comedy.
Dexter.. Season 1-4 was absolutely fantastic. Then.. It just went to hell.
Now I can't even watch any episodes without thinking a FUCKING LUMBERJACK!!!
Battlestar Galactica. One of my most favourite shows ever, but the ending ruined it for me.
Loved the show at the time, but know enough that there is plenty of terrible in it for 10 seasons. I could never watch the whole thing again.
The Leftovers. It was a wild and emotionally exhausting ride. I love it with all my heart, but I am not planning on a re-watch anytime soon.
Enjoyed the majority of Twin Peaks: The Return and discussing it weekly as it aired was insanely fun, but I have no interest in rewatching it. Maybe in a few years.
The Leftovers and Six Feet Under are both fantastic but very depressing so I’m good on them as well.
Just for fun, the shows I find the most joy in rewatching are LOST, Angel/Buffy, P&R, and The Office. My comfort shows.
