I liked it a lot. Had the advantage of UK time zone (for once!) so spent the day with them on Sunday
It works as a whole piece, rather than discrete episodes, so don't give up. I also think it will stand up to repeated viewings as it is pretty dense.
That said, it could maeby have been edited better to be a bit less flabby but I guess Mitch Hurwitz et al were taking advantage of not having to do that because it's Netflix and not 20 minutes of broadcast TV.
And personally my favorite characters were towards the back of the series so I felt like I was waiting a bit through a few of the others episodes.
But I loved it and I love this new Netflix model of distribution and freedom (for viewer and creators)
