I thought it was average and if the Worf plotline hadn't been redeemed a bit at the end I might have gone lower than that.
I think half the problem is a lot of the characters aren't particularly engaging and we've been here before with a lot of the action sequences - the Nausican, Okona, Lavelle, the inhabitants of the station in danger, none of them really caught my interest or felt particularly new or original in their use.
Other returnees like Wildman and Lavelle didn't really feel like the characters we knew before, partly due a shift to everyone speaking a bit more informally than usual in Trek (though I didn't see any vulgar language!) which I don't have a massive issue with but alongside so many odd references about getting paid or salaries it jarred somewhat. Same with what was done to the Enterprise to stop them getting involved, I didn't really buy it or how poorly the crew handled it.
All that time might have been better spent doing more with the crew, Smrhova gets a lot of focus, picking up a thread about her feeling she isn't as capable as others. Great to see it touched on again as she has been all but ignored since the last time David Mack wrote her but it doesn't really go anywhere and she doesn't really achieve much other than be angry most of the time. When it is hinted that Worf could make her his First Officer in the future you have to wonder why he would bother. Though saying that I was quite uncomfortable as to her last scene, I really wish that hadn't happened.
Worf as Captain gets some great stuff right at the end though before that he barely makes an impact. The odd Geordi revelation at the end might have worked better if there had been any sense of that previously. No one else, other than Picard, really gets anything to do.
The Picard thread works best though it feels a bit predictable - we know he didn't go as far as he has been accused so it doesn't feel as big a challenge as it might have. Phillipa Louvois may not have been the most likeable character but she deserves better than being written as a one note vengeful harpy as she is here. I think absolutely there should be people who find what Picard did unacceptable but a bit more shade in their characterisation, and a bit less willingness to stretch the legality of the situation themselves might have been nice.
