I will keep this simple.
The first few minutes hold the secret to the show's failure. Tony looks out the window and sees his neighbor, a naked older woman, about to get dressed. She has bigger and nicer breasts than her UK counterpart, but we do not see these breasts. I hope you understand that this is not about breasts but solely a metaphor for the whole show.
Even though, some minor details were brushed up, the rest plays out exactly the same as the UK version; only more rushed and soulless. Tony, the main protagonist of the first episode, is supposed to be manipulative but interesting. In this version, he's merely a douche.
This show lacks new ideas as well the vigor and the originality from its predecessor. A total failure.
