Possible Rogue One spoiler below.
I hated Nemesis when I saw it in the theaters. I came out and told my husband "I don't want my money back. I want my time back that I spent watching that." So, skip to this past January 2017, and Nemesis was on Netflix. I had pretty much forgotten about the movie and been able to Un-Watch it. I stepped onto my treadmill and put on Nemesis to walk to. By the time it was over, I hated it more than the first time I saw it.
When I saw it in theaters, I didn't have the luxury of having just watched the whole series in an online binge-watch. So, seeing it from that angle made it so clear just how out of character everyone acted, how bad the writing was, and the massive holes in the plot. It has a few decent scenes, but when just about all the Deleted Scenes are better than most of the movie... that says a lot.
And yes to the "It's the Picard and Data show" sentiment. I do love both those characters, but it was like all the other characters didn't have to be there. In fact, all the characters, including Picard and Data, could have been replaced by generic characters as a non-Trek film and it would make no difference. Data's death is cheap with no impact. (For a good death: Spock in Wrath of Khan, K2 in Rogue One, Wash and Book in Serenity, Roy Batty of Bladerunner).
Just my opinion, of course.
