Weird tonal shifts, weird editing choices, like, jumping back and forth between past, present, and future to a degree where you get lost to as what is happening when, switching between scenes too often so you never get a feel of the urgency or danger they're in, and in a way that you never really get to know - or care about - the characters.
Even the handful of actors I normally like are horribly miscast, as is almost everyone, and especially the girl playing Fran Goldsmith (Odessa Young, the first I've ever seen of her) is atrocious.
I may give it an episode or two more before deciding if I want to finish it.
