How often do you rewatch?

very rarely, only tihng i've rewatched is aot s1-to s3 and Haikyuu s1-s3(which I haven't updated for some reason)

Same as OP.
I rewatched only if I really want to.
Only anime I've rewatched completely are
Steins;Gate
Sword of the Stranger(min.5 times).

I generally don't rewatch things, and when I do I usually don't even finish rewatching... The only exception was when I watched Devilman Crybaby in high school. Binged the whole thing in one night and rewatched it over the course of a few days.

Whenever I realize I have forgotten 99% of a show and I have a rather high rating for it or a low rating that challenges the average by a large margin.

As an example my record is definetely Ichiban Ushiro no Daimaou
Ichiban Ushiro no Daimaou
I must have watched this show at least 4 times and I always end up giving it a 70 despite forgetting everything about it in about half a year.

i don’t usually rewatch stuff, beacuse i have over 140 anime in my planning list, so there is always something to watch.

i rewatch a lot, if it is a show i really like then i dont mind rewatching it evry other month

Almost never. I feel like it's a bit of a waste. So unless I completely forgot everything about the show, or need to refresh the memory before the new season, I'd rather watch something new.

With the exception of comedy shows, of which I can rewatch certain scenes or even episodes.

Never. The most I do is watch clips of some of my favorite scenes on YouTube or something.

My rewatching time is almost equal as my normal ones xD

when i feel like doing so

I rewatch a lot. It's usually because there was something major that I was unclear on, or I want to re-experience a feeling with something I already know I like rather than taking chances with a new show that will probably leave me unsatisfied.

If it's funny anime then i just watch it like 2-3 times. If it's like action then i just youtube it's action scenes

Never done so before.

I'm so indecisive to choose for a new anime to watch I start watching anime I've already seen. If you check my anime list you can see I've watched some of them 4 or 5 times.
I like finding new details in my favorites and getting an even better understanding of the story / character development.

I rewatch some movies every year, mostly Studio Ghibli ones.

I just rewatch my favorite episodes, instead of rewatching the whole series. I honestly prefer watching something new.

I rewatch something that I either loved a lot, or couldn't appreciate enough in just one watch. But still I have rewatched just a few anime, so I don't rewatch very often.

Rarely I do, I have been watching anime since 2015 and only done 15 rewatches, not counting movies.

All the time really, im always in the mood to relive my favorite shows. it varies from show to show but rewatching an anime and enjoying it just as much the 2nd time is a great feeling.

i've been watching anime for close to half a year and i've only really rewatched AoT (once) and Demon Slayer (twice).
but a lot of the time I like to go watch and watch specific clips like a fight scene or a singular episode.
sometimes compilations of character moments or something

Only when i watch a new production of a series i watched several years ago. For exemple Mahoka (The Irregular at Magic High School).
Why ? Because i want to be immersed the more i can inside the series and sometimes i just forgot multiple part of the intrigues or part of story etc etc.

―――­­―――­­―――­­―――­­―――­­―――­­―――­­―――­­―――­­―――
The only exceptions are for movie (especially ghibli) and Elfen Lied.

Why ? Well its enough short to be rewatched

Rare, i only rewatch specific episodes of animes i truly love. And there's a lot of anime i plan to watch, though im so slow at watching them

Wrapped up my 10th K-On! rewatch and began a 5th Hibike! rewatch recently. I'm not kidding.

I rewatch Naruto and Dragon Ball like every two years, but now I don't really feel like watching any of them now, maybe Gintama sometimes soon since I stopped before the last arc and forgot most of things before

The only time I watch anime fully is when its been a long time since I watched it. For example I rewatched sao 2 years ago because it had been around 4-5 years since my first watch.

There was an outlier tho which was the rebroadcast of Re:Zero season 1, watched the full thing through and enjoyed it even more
