Why people didn't like the first scene of season 2.
The sorority sisters in the opening of season 1 were realistic in a sense that they were extremely exaggerated versions of a stereotype. Everyone thinks that Sorority girls are dumb and shallow and love to party. As the audience we have a preconceived notion that sorority girls prioritise partying over being good people, and this is essentially what the writers were playing on. In fact, all of the funniest characters are over the top versions of common stereotypes including Chad, Denise and Munsch.
In most people's minds the stereotypical doctor, however, is smart, caring and professional. The opening scene of season 2 was not an extremely exaggerated stereotype. In fact he was the opposite of a stereotype and the opposite of everything people perceive doctor's to be. Perhaps this was supposed to be humorous but I don't think it landed for a lot of people. The writing just wasn't as layered and smart, and it had a different comedic voice in my opinion.
I personally would've liked the doctor a lot more if the writers played on the common trope of the crazy experimental doctor. He could've been experimenting on his patients or killing them to harvest and sell their organs, rather than killing them just so he can party. It would've been more in character. It also would've been darker but could've been kept funny with the dialogue. I think that would be much more similar in tone to season 1. (On a side note, these alternatives all involve the doctor dumping a dead patient rather than a live patient in the swamp which could potentially be a major plot point and why they didn't go with these options)
I would describe the characters in the opening of season 1 as "over the top" whereas I would describe season 2's as "silly".
I'm a firm believer in not taking this show seriously, however. I'm going to continue to watch and enjoy it for what it is and what it gets right. Hopefully they keep the silliness to a minimum though.
Although, I was high when I watched this.
