The same weekend I saw both Captain America: The Winter Soldier and The Raid 2 -- prompting this piece for NPR Monkey See -- my pal Glen Weldon showed me the mostly-animated G.I. Joe episode of Community. The show got a lot of mileage out of the fact that nobody ever got killed in that war cartoon, wherein an elite American military unit fought a uniformed army of terrorists to a stalemate every 21 minutes using ray guns.
The G.I. Joe comic book, meanwhile, took a realistic approach to firearms. Characters sometimes got killed, too, although not very often. It didn't get me hooked on guns, thankfully, but it got me hooked on comics. It was also pretty clearly a gateway drug to more sophisticated depictions of violence in movies and TV.
