In no particular order, I'd probably pick Terminator 2, Die Hard, Robocop, The Dark Knight, Heat, Kill Bill 1+2, District 9, The Crow (been awhile since I've seen it though), Speed, and maybe John Wick.
There's probably quite a few I've missed out on, especially foreign action films.
What are your picks, either popular or obscure?
Starship Troopers. Great movie, also great litmus test - be wary of anyone who says they hated the movie and preferred the book.
The Fugitive. Two mains are kind of libertarian ubermensch wet dreams, but it has a lot of great sequences (like history's most absurd bus crash) and the main theme slaps.
The only weird thing to me about the movie, and most Starship Troopers media in general, is how they turned arachnids into animals, when in the book they were smart as humans and used weapons.
I believe that's partly because the movie began as a sci-fi action film called something like "Bug Hunt at Outpost 42," and the book tie-in was added later.
I also think making the bugs look like inhuman monsters works better, because it takes the pressure off of the protagonists to try and reach out to them and communicate, instead of waging a genocidal war of extermination. The subtext implies that the bugs are indeed intelligent, but that possibility never even occurs to us, until it serves the narrative ("It's afraid!").
Also be wary of anyone who loves the movie too much. Some Fash take it at face value.
