That's right, you heard me.
SPOILER WARNING for anyone who hasn't seen any of these Disney Plus shows, but if you haven't seen them you shouldn't be reading this.
Now, to be fair, The Mandalorian is not the same type of series even though it is also in the Star Wars fictional universe.
The Mandalorian is basically a space Western, aka interstellar Clint Eastwood duking it out cowboys and Indians style like a vigilante in a town with a crooked sheriff and cartoonish villains, most of them alien creatures, but also some zealous followers of the fallen Empire fighting the New Republic. To me, Bill Burr is the highlight of the show.
Andor, on the other hand, is a cloak-and-dagger spy thriller showing us both the high society politics and gritty street level view of how a violent brewing insurgency would look against a galactic-sized fascist dictatorship hellbent on crushing conquered peoples and lower castes with brutal authoritarianism, excessive force, and unwarrantedly punitive measures. All while focusing on a character who's a thief but an honest one trying to do what he can to survive while sticking it to the Empire. Plus, the supporting cast of famous actors Forest Whitaker, Stellan Skarsgard, and Andy Serkis bring this rough-and-tumble story to life.
To be honest, though, The Book of Boba Fett is even dumber/cheesier than The Mandalorian and yet it's more satisfying with "hell yeah" moments whenever Boba Fett beats the hell out of a monster or a mob boss and gains the respect of his peers. At least the colorful characters in Boba Fett aren't humorless one-dimensional snooze fests like the various Mandalorians in exile from their home planet. Puppet Baby Yoda, i.e. Grogu, also provides enough cheesiness to almost level it out with the Jaba the Hutt creatures in Boba Fett. The latter also competes with some of its own decent cameos, like actor Danny Trejo being a "rancor" animal trainer.
Obi-Wan Kenobi is a slightly more serious show than Mando and is almost as good as Andor, but Andor is still better. They both take place during The Empire and both focus on the rebellion against it. However, Obi-Wan Kenobi has that whimsical quality to it like the Star Wars films, which isn't a bad thing for fan service, whereas Andor is far darker, more dystopian, and more realistic (as realistic as one can be in a science fiction setting). The whole prison sequence is terrifying, with the theme of having all your rights taken away and you just becoming a chattel slave working yourself to death like it's the Holocaust, only it's just random people who committed petty crimes getting lost in the system. There's nothing quite like it in all the Star Wars media I've seen, especially the season 1 finale where the amazing posthumous recorded speech of Cassian's mother causes a riot during a funeral procession that turns into a full blown insurrection.
Honestly, give the show a chance, you'll probably like it even if you dislike The Mandalorian for its cheesiness. I still like that show, and Pedro Pascal rules and everything, but in all honesty it's not a great show. It's average compared to Andor, which sadly will only have one more season.
