I'm going to agree with Owen; there doesn't seem much point in this show - apart from cashing in on the Friends brand.
We've had ten years of jokes about Joey pulling women, ten years of jokes about Joey failing auditions, do we really need any more?
Which means if this is ever going to be more than a cheap Friends cash-in, it's going to have to rely on the new characters, and - judging by the two eps I've seen - that's a problem.
Joey's agent is very annoying and not at all funny!
The blond neighbour seems very bland, and as someone else said, a bit of a Monica clone. I assume her (invisible) husband will somehow go away so Joey can at least try to sleep with her, otherwise why is she there?
The nephew is clearly supposed to be the new Chandler, except not as funny and with a lot of Ross-like geekiness. The thing that bothers me about him is that most of the second episode was about him being too much of a nerdy geek to pull women, but the actor playing him is just too good looking for this to be believable.
I don't remember Gina Tribbiani's appearance in Friends. Was there ever a mention of Joey having a sister who had a baby at 16? So far, she's the best new character (IMHO), but her always being around is going to get a bit silly.
All in all, the first couple of eps were OK, but no more that OK. Hopefully it will get better.
BTW, you can't see the stars in LA (or any other big city) because all the light in the foreground makes it impossible to see the stars.
