Andron is a 2016 film about a dystopian future where the population volunteers to play a game to the death for freedom and riches. That seems to be a common theme in SF films now. The population are little more than slaves of the 9 corporations that run things, their big entertainment is the shitty TV they watch. It's interactive TV, you can hook up with a player in the game and see what he sees on the popup display in front of your eyes. If the player dies while you're watching, you die too. Nice, huh. Keeps the pop down. Most of the film is people running about a dirty warehouse with a few futuristic (ha, ha) props in place. Alex Baldwin controls the game and Danny Glover in the Chancellor. They haven't got much to do in the film other than show the heads of the corporations are scum. It's all pretty much what you've seen before but more poorly presented.
Monstroid - It Came From The Lake is a 1980 film about a monster in a lake. I'd seen it back in 1995 but had forgotten everything about it. It's a pretty typical below average low-budget monster movie and there's hardly any SF, other than pollution creating or changing the monster. Some ugly Americans have a plant that is being protested by the locals. That all takes up a lot of story time.
There's not much good to say about the movie. Nice to see John Carradine. The monster is a big head that does enough of the job. They do blow the big guy up but that's hardly much of a bang up ending.
The Amazing Captain Nemo is a shortened feature film version of a 1978 TV miniseries called The Return Of Captain Nemo. I doubt I saw it back then, I was in the middle of moving in 1978 and missed a lot of TV. It would have been a good thing, it's pretty poor.
