I've watched the first six episodes since yesterday.
I think it is a great show, so realistic and not over the top in any way. Before the premiere I thought I'd like Lily Tomlin's character more but for now I like Jane Fonda's character better but both are generally so sweet.

I love how all of the characters are trying to adapt to new situation but it'd be great if we had some background info about the families

would be much appreciated. Also I'd like to see children interacting with each other more often, among them my favorite is Cayote, he is like his mother

And I wish the guy from Enlisted would used better and more often but I guess that won't happen.
All in all so far it is better, less messy and less try-hard than Transparent. I don't understand the negative response among the critics.
