Specifically, the actor who played the wealthy mom was not great. I'm not saying that Mizuno should be up for an Emmy, but she doesn't detract from the show and the scene in the house with Pill was brilliant.
Pill was great, not Mizuno.
The scene from last week's episode between Sergei and Lily was awful too.
Still very interested in the series and it has been fantastic so far, but it is far from perfect.
