I'd still give it a solid 8 overall. I just appreciate the main character so much. Usually when you have someone who's thing is that they're cynical, the characterization is a strawman. (Ditto most other highly unusual people.) Wednesday feels like a real person. Yes, she's also compeletely overpowered and many of the anecdotes are over the top, but her actual actions throughout the series are for the most part completely logical. It's everyone else who's being stupid and wasting time on things that don't matter; she's just trying to find the monster. I do love people who decide on the best thing to do and then to that thing, without all the usual bs.
Also, the cello scenes in e1 and e3. That was perfection.
Well, I like the aesthetics, and as such I agree that the cello scenes are awesome. I have issues with Wednesday's characterization though. I would have liked it to go one of two ways: She remains the cynical genius psychopath throughout (which I think would be most in line with the franchise, though I haven't watched much Addams Family), or else she realizes that she's not as special as she thinks and has to come to terms with the fact that's she's just a normal teenager like everyone else.
The show, I feel, tries to have it both ways: She keeps her cynical comments and genius but also learns the value of friendship (a cliche if ever there was one). Which gives neither interesting character growth nor a true outsider, but just a kind of run-of-the-mill Tim Burton character.
That's my main complaint. There are some smaller gripes, like the kind of desperate attempts at allegory (Enid's whole trans werewolf arc for example), or some weird plot contrivances. It's still entertaining enough but if I'd have to give a rating, it would probably not exceed a 6.
