Not OP. Making guesses here…
- Idiocracy = humanity becomes catastrophically stupid / institutions decay
- The Matrix = humans are reduced to resources inside a machine-controlled system
- Terminator = machines actively exterminate humanity
Idiocracy X Matrix: People are dumb & happy, caused their own problems, so maybe Wall-E?
Idiocracy X Terminator: Our stupidity puts us in a bad situation of creating our own demise. Dr. Strangelove perhaps?
Matrix X Termiantor: Machine dominate humanity out of existence. The cross here feels shallow, like these films are pretty similar with regards to humans, machines, and the outcome. Oblivon (2013) kinda works? 9 could also work.
Center: I dunno, Robocop? Systems failing, corporations suck, lethal machines. Honestly Black Mirror likely wins, but it’s too broad a series.
