RoboCop (the original, duh). It just has... everything. Action, satire, hilarious amounts of gore, and more!
Also, Dredd (not to be confused with the 1995 Judge Dredd movie which was bleh). I don't know why, the movie isn't all that deep or anything, but it's just the most solid sci-fi action movie I can think of that I like to watch. Well, technically Blade Runner 2049 is a better movie but it's also almost three hours long while Dredd is a mere 90 minutes, so yeah. @w@
