Although it's still not fantastic, the second installment in this new Netflix series is manifestly an improvement upon the first, easing in to the story with far less difficulty & enjoying itself a bit more, now the unenviably hard job of world building / obligatory establishment is mostly completed.
However, I'm still not entirely convinced the creators are fully embracing the "Addams Family" concept, nor are they demonstrating their ability to understand why the joke (that their entire premise is based upon) is funny; Wednesday, Morticia, Uncle Fester & Gomez etc. Are all utterly depraved, sadistic & derive enjoyment from things you'd typically associate as being "sinister" - hence, we laugh at the absurdity of their behaviours & reactions to situations a "normal" person would normally find unsettling - due to how unusual & peculiar their actions are. Therefore, it's amusing seeing how their family interacts in a concentrated space, as they're utterly unrelatable & equally, cannot relate to us. In summary, the humour's borne from the fact that they subvert expectations (in a tongue-in-cheek manner) & defy the conventions most others would abide by in any fictional tale being told.
The creative decision to make the title protagonist sympathetic is resultantly a total contradiction & defeats the basic point of her entire characterisation, so although I understand their desire to cultivate a narrative which audiences can emotionally invest themselves in, the plot centres around the development of a lead who (though they may resemble her) is arguably not "Wednesday Addams".
