No Mutants Allowed

In seasons 1 and 2 Rick had several moments of vulnerability and failure, even when he was right he wasn't unfalible, on the first episodes is even him fucking up so much their only plan is to abandon the entire dimension.
In season 3 there an episode where he defeats the villain off screen and it ends with a party in his name.

I disagree. I read Rick in season 3 as being someone who could do just about anything but ended up alienating his entire family in the process. There were absolutely moments of vulnerability there, as well as questioning whether unlimited power is worth the cost. Rick wasn't just an omnipotent badass for the incels' sake.

But he was, he constantly solved things singlehandedly, from the premiere to the season finale. Hell there is an entire episode (Pickle Rick) where he is just a badass action hero who destroys anything and his supposed moral defeat at the end doesn't even stick.

The Avengers parody episode literally has him being so badass that he defeats the villain off screen and shows up all the Avengers because he is so cool. Morty even acts very Rick-like in that episode to show he is "cool now". Few episodes of season 3 had him have any kind of vulnerability.

I stopped watching that show after season 1 tbh

The season premiere was initially fun but it spelled the direction the season was gonna take, with the discarding Rick's emotional arc from the previous season to reframe everything as all part of his plan. The incel fuckboys and even the writers even latched on hard to the Sezchuan sauce gag.

Yes, he was badass and all-powerful, and that's the point. He's the smartest person in the universe, one of the most powerful, his family idolizes him, and all of his greatest enemies have been beaten. He holds all of the cards, and despite that, he still almost loses everything.
