Yes, there are good ones, they just don’t market themselves as ‘isekai’ because they have other stuff going on as well and they advertise as that instead.

Some of my favorite isekais are:

• A Kid in King Arthur’s Court

• Space Jam

• Jumanji

• The Wizard of Oz

• Army of Darkness

• Last Action Hero

• Futurama

And they’re not even anime.

I personally loved The Saga od Tanys the Evil. it’s an isekai where the protagonist is reincarnated in the equivalent of Germany during the first world war but with mages. very interesting

don’t think i’ve seen ascendance of a bookworm in here yet? high suggest although i’m only reading the manga and not the ln or watching the anime

also obvious .hack shill

Alice in Wonderland.

Space Jam.

Log Horizon That Time I Got Reincarnated as a Slime Overlord

I can’t think of any other good ones and I’ve seen over a dozen.

Isekai are popular and relatively easy to write; you don’t need to come up with elaborate settings, magic systems etc., you can just handwave it as ‘guy enters generic videogame world’. This attracts a lot of untalented writers trying either to make a quick buck or pour out their power fantasies, oversaturating the genre with a lot of shit.

But amidst that shit there are some nice gems, I recommend Hametsu Flag, I Favor the Villainess, The Magical Revolution and This Isekai Maid is Starting a Union.

I like Overlord mainly because it’s somewhat of a subversion of the genre. It’s SAO but the MC is max level in the game and has everything, so he needs to find new challenges.

Grimgar of Fantasy and Ash. The anime only got one season but it was pretty solid. I’m not sure if the manga/light novels are as good but there’s at least more of them.

Sword Art Online taught publishers that people really want bland wish-fulfillment stuff where the hero just steamrolls any problems that shows up and then gets all the girls. Of course SAO had other things going for it, like good animation and a great soundtrack, but that isn’t what they can easily copy.

Shield Hero taught publishers that people want that but also with the main character owning slaves for some reason.

Anyways, due to these two things isekai has been almost universally weird af lately. That said, it’s not all bad. I liked The Eminence in Shadow, but I recommend the manga adaptation over the anime. The mangaka just has a really good sense of comedic timing. I’ve also heard good things about Shangri-la Frontier. There are a few more good isekai if you look at the pre-SAO era. Vision of Escaflowne was really good, as long as you come in with the expectation that this is a shoujo mech isekai so it’ll have a somewhat different feel to it.

Of course, that’s if you’re stuck on wanting to watch/read isekai. There’s been tons of great stuff coming out every year that has nothing to do with isekai. My favorites from the last 5 years have been:

• 2020 - Keep Your Hands Off Eizouken! - A team of high school girls form a club and set out to make whatever anime they can with their limited resources
• 2021 - Vivy -Fluorite Eye’s Song- - The first AI-powered humanoid robot tries to prevent the robot apocalypse
• 2022 - Chainsaw Man - A sad boy has a wild (and bad) time. Honorable mentions go to Spy x Family and Bocchi the Rock. It was a strong year.
• 2023 - Skip and Loafer - A book-smart girl from the country moves to Tokyo for a better high school and adapts to city life
• 2024 - LOOK BACK - A story about 2 artists. Honestly this year was stacked too, so honorable mentions go to Bang Brave Bang Bravern! (big gay robots), DAN DA DAN (romance, yokai, and aliens), and Delicious in Dungeon/Dungeon Meshi (traditional fantasy, but really well executed).

Notably even though every year a whole pile of isekai gets released not one of them made it into that list. I’d avoid them as a general rule for a while, except when you hear a lot of people recommending a specific specimen.

there is way more bad than good, because SAO got popular years ago and showed publishers that isekai fans will accept absolute slop, and not even the kinda slop you might like on a bad day. That said, there are some real good ones out there. In addition to what other people have said, I’d like to point out what should have gotten big instead of SAO; Log Horizon. It’s also about getting trapped in a game but log is generally about dealing with the world and the implications of it coming to life . For a minor spoiler:

To mention one not already said.

ShangriLaFrontier

Isekais are so overdone, that even parodies are overdone. SLF doesn’t take itself seriously but also doesn’t make fun of the genre. Instead it’s like it wants to go “okay, but being OP in a VR world is hella fun”, and shows the characters enjoying being OP and fighting equally OP enemies. I especially enjoy the banter between the closest friends as the heckle each other. My only complaint would be, protagonist friends are also OP in their own ways but we never see them win over protagonist on screen, just implied during conversation.

Konasuba. Since it’s a parody of the genre. I’ve avoided everything else in the genre.

I think the Chronicles of Narnia is probably the best isekai.
