Movies you loved as a kid that weren't made for kids

We all had favorite movies as kids that were made with kids in mind as a target audience, but what are the movies you loved that weren't geared toward kids? For me, it was Executive Decision (1996). The stealth jet, the gadgets, the tuxedo—I couldn't get enough of it. Definitely not a movie I'd describe as kid-oriented or even kid-friendly, but that didn't stop me from being obsessed with it. What are your movies like this?
