I really enjoyed that, it was definitely the most intriguing opening episode in a while and I'm loving the soundtrack.
Gaga's surprised me so far, she hasn't been given a lot to do but I think she's left a good impression on me so far. She's quite convincing in the role. I don't see much potential for Donovan's character though and I'm not keen on Iris' character, their storyline is a bit boring to me at the moment. I think it's just gonna be somewhat similar to the story of Constance and Tate in Season 1. I hope Evan and Finn's characters brings out something interesting in them.
I think Sally's the most intriguing part of the show so far.
