I don't know if anyone else has started watching this yet, but I watched the first two episodes last night and hugely enjoyed them. So far, the show is fulfilling its promise beautifully. There's a nice mystery developing, with lots of nice red herrings and a couple of excellent WTF moments. Jenna Ortega is nailing Wednesday's wonderful deadpan delivery as well as the perfect occasional hint of underlying vulnerability and warmth.
The 'magical school' environment is not hugely original, to be sure, but beautifully creepy and gothic, and the main student characters - are they friends, rivals, deadly enemies? - are all interesting and well-played... room for lots of development. The relationship between Wednesday and Thing is fabulous and really nicely extended from the movies, and I really liked the characterisations of the rest of the family (though we only see that briefly at the beginning of episode one). Gwendoline Christie is splendidly ambiguous, alternating between regal authority and silky menace. And I'm delighted that Christina Ricci seems to have far more of an important role than the cameo I expected.
It's creepy, kooky, and altogether ooky and really does have the true Addams family vibe (watch out for the clever integration of the iconic double finger-click). And Uncle Fester still to come! All in all, a very promising start, and I'm already hooked!
