"Winchester" is a straight up horror movie that is "based on real events". That is, the rifles are real, the company is real, Sarah Wincester is real, the house is real, and the 1906 San Francisco earthquake is real. The actual plot of the movie is pure fiction. Still, it works pretty well, and Helen Mirren is always worth watching.
"Maze Runner: The Death Cure" is the last entry in this goofy series. The character work remains pretty good, the world remains relentlessly stupid, and the story craft is more than a little lame.
"Black Panther" is, to quote Columbia from RHPS, "OK." The cast and character work are excellent, the effects are overblown and kind of pointless, the main villain comes painfully close to being three-dimensional before he lapses into mustache twirling, the title character suffers from perfection-is-boring syndrome at near-Superman levels (made significantly more tolerable by the amazing Chadwick Boseman), the director has no clue how to sell misdirection, and the movie is a good 30 minutes longer than it really needs to be. So middle of MCU pack, maybe a B- overall, but the material for an A movie was there.
In other news, I went to a convention last weekend, and managed to play a couple of RPGs without freaking out. Go, me. Details here: https://uncle-gnoll.livejournal.com/
