What’s an anime you enjoyed the first time but couldn’t get through a rewatch?

Several years ago I watched Free!, I really enjoyed it (and the bodies), mainly because the drama was interesting and gripping. I had made it through to the latest season at that point in time (season 3 or 4).

However, I tried to rewatch it over lockdown and it just made me cringe it was terrible. I ended up dropping it on the first or second episode, and I haven’t watched it since.

So I was just wondering if anyone else has had an anime they watched and enjoyed, that they couldn’t get through a rewatch?
