I agree the English characters are one-dimensional, perhaps because they barely feature so we can't 'know' them yet. I don't think having these short episodes - 27 minutes this week - was a good choice.
Episode nine was another mostly forgettable one. I can't get invested in Aidan and Carrie because they're so ill-suited. The most interesting thing was the way Carrie had her hair in the last scene.
Anthony and Gia's relationship is tedious and predictable, and I get the feeling Patti LuPone's heart isn't in this really, she seems a bit underpowered or vacant. But now that Gia has threatened to financially cut off Giuseppe, I wonder if Anthony will soon get his heart broken - Giuseppe's facial expression seemed to say he's going to take the money and run.
I'm kind of glad there's only three episodes left until it finishes.
