The main points seem to be that the show is joyless, and missing all the fun and optimism and thought provoking ideas and stories that made tng great. The dialogue is overly quippy and everyone is depressed. I understand you like the show but you disagree with those specific points?
I wouldn't say it's joyless - I've laughed out loud on several occasions during this series. Jurati is hilarious, as are Raffi and Seven, and the younger Guinan is sassy to a fault. Picard is still the same wise, optimistic captain he always was, just older.
The premise is, in many ways, a retread of several previous TOS/TNG stories (Time's Arrow, The Voyage Home, City On The Edge Of Forever, Assignment Earth), but doesn't suffer because of it - it embraces the connections, like the punk guy on the bus (another fun and far from joyless moment), the references to Gary Seven, and so on.
I shall reserve my judgement on the story arc as a whole until the end of the series (I need to see what Q's resolution is) but, other than some pacing issues, I think it's been a great series so far.
