Don't listen to the control freaks and geeks....It is a great sci-fi ride! First off, am I the quintessential STNG fan? Nope. I only watched the entire series more times than I care to recount. (a "true" fan could tell you exactly how many times and do it in Borgian Binary no doubt) Look, if you are the totally self involved, control freak, who has to have everything their way, then sure, this will not be your cup of Romulan Ale. BUT, if you are a more selfless fan, who appreciates the fact that the stars of the original series are even willing to take their fans to a few more places that no fan has gone before....then this is rather like a refreshing cup of Earl Gray served up hot in a day and age that's kind of not.
I find the show truly 'engaging', Stewart comports himself well, as do all the stars of the original series appearing thus far (7 episodes in). The new actors have clearly done their homework here, and blend in well, I find. But then, I'm capable of having an open mind. If you're apt to go into this with your conflated ego on your shoulder, then maybe take a hard pass, don't be an ass, and go play some 3D chess on your daddy's collector's set.
Picard is a Hit and I hope it gets a second season, or as many as acting legend, Patrick Stewart is willing to do!
Live long, and prosper.
