In short, a MITH movie has our heroes trapped in a space due to a sin not of their making, there's a monster, and at least one character who is a wounded half-man harbinger of doom.
Once you know the ten categories, movies become pretty predictable after the first reel or so, so maybe you don't want to learn them.
e.x.
Jurassic Park - Stuck on an island full of dinosaurs
Congo - Stuck in a lost city full of deadly intelligent apes
Sphere - Stuck in an alien ship on the bottom of the ocean
The whole genre is "Lost World" and goes all the way back to King Solomon's Mines in the 1800s.
The other seasons are made confusing seemingly on purpose without adding to the story.
In TV this form is often referred to as a "bottle episode"[1], and there's at least one article describing Alien as a "bottle movie"[2]. Presumably, this was done to maximize what could be done with its $11M (!) budget.
I seem to recall ebcountering one that is somewhat more specific than TV Tropes’ “Closed Circle” [0] but less specific than “Ten Little Murder Victims” [1] that fits this, but can’t put my finger on it right now.
