Well, I mean, she did set a bunch of piranhas loose on the swim team.i have many of the same thoughts as you but overall i did not enjoy the series. for me the biggest stumbling block was them trying to create Lore and Grounding The Addams. in the 90s movies, everything exists for the sake of a joke, you're not supposed to think too hard about the logistics, you're just supposed to roll with it. but Wednesday is like, "oh no, gomez might have committed a murder and that's bad, and he might go to jail for that and that's also bad" and "Wednesday goes to an Edgar Allen Poe Ghoul School For Babby Monsters, but everyone thinks she's weird for being a goth, and so the Addams are still considered weirdos even amongst the Weirdos," and you have Wednesday herself acting like the 90s movie character where she talks about serial killings and being macabre and whatnot, all while she's trying to stop a serial killer (and like, one of the worst of her actual actions is sending mouse traps to an editor who didn't like her book), so it sort of deflates the character from being a fun part of an ensemble to a really dorky edgelord teen who we're supposed to think is the coolest badass around.
jenna ortega did a good job, but oof the material.
