Legion was a short lived masterpiece on FX from 2017-19 that is a near perfect show…. and next to no one watched it. It was created by Noah Hawley (of Fargo fame) and based the Marvel comics by Chris Claremont and Bill Sienkiewicz - and it stands singularly on its own in tone, storytelling, writing, and aesthetic from the MCU (and tv in general, really).
It’s such a hauntingly good show that was capable of terrifying you, absolutely breaking your heart, and making you die of laughter- usually all in one episode. and of course, it features an incredible cast: Aubrey Plaza (on a whole other level), Dan Stevens, Bill Irwin, Jemaine Clement, Jean Smart, Hamish Linklater, Nevid Negahban, and more.
It’s on Hulu, and I recommend not binge watching for your own peace of mind.
