I totally loved season 1. While there were some flaws, none of them really mattered to me because the show was very engaging so I wasn't looking at the plot holes, for example.

However, season 2 is a whole other deal.

The characters and their relationships didn't have any development and were boring. Having a partner of a different sex compared to your ex is not character development. Being a cult leader is not character development. Having a girlfriend... you get the point.

Most of the time was spent on side stories that didn't matter and were poorly done. The social issues had no connection to the main story or characters and were written in a very superficial way. Boring and unnecessary.

The new characters are a snoozefest and completely forgettable. On top of that, half the interesting ones from S1 are gone.

Everything is dragged out simply to fill the episodes. The writing was so bad it's difficult to even say what the climax of the season was supposed to be. Things just happen, that's it. A lot of the scenes were so poorly done that you can only feel bad for the actors who seem to be just standing there not knowing what to do. A couple of times I was even confused about what was going on because I couldn't read what they were trying to convey. There were several long scenes that didn't serve any purpose, cinematic or otherwise, like walking into a building for 30 seconds. I just felt like fast-forwarding through them.

There was a lot of gore just thrown in for no reason. "Hey, we don't have a descent plot, well-written scenes, or character development, but here's some severed body parts... oh, and don't forget the fart jokes! Enjoy!"

We did get 2-3 enjoyable family scenes but that's about it. If I wasn't already very invested in the characters, I wouldn't watch this train wreck. Season 1 was 8/10 for me, season 2 is 4/10 at best.

Edit: After writing this, I watched the last two episodes of S1. Each scene is interesting, it has weight, emotion, direction. The characters are connecting with each other and are serving as a mirror or a counter point to the arc of someone else. The music enhances every important moment because there is actually something to enhance, and it's used perfectly as a foreshadowing device (because there are actual things to foreshadow). With S2 I didn't see any of that and the epic end theme always felt undeserved. I honestly have no clue how people are giving S2 good reviews...
