I'm four eps in, and I think it's brilliant. Time travel/loops are a couple of my favorite tropes, and, while I'm enjoying that part of it immensely, I was pleasantly surprised with Nadja's character. She's brash and insecure and sort of hyper, and it all feels so real, like I already know this incredibly faceted person. Not all parts of her are likable, but they feel real and earned.

Also, kudos to the casting people for rediscovering Elizabeth Ashley.
