I actually really enjoy these two movies. That said, they've aged pretty badly... Escape From New York and Escape From L.A.
First of all... story hasn't aged well. The first film, Escape From New York is set in the far off year... 1997... when Manhattan Island has been turned into a maximum security prison and World War III has been going on for a few years. Then there's the special effects... which at the time were pretty good (like the navigational computer display in Plissken's glider, which wasn't even computer animated), but by today's standards look incredibly dated. Then there's the movie's weapons... the police in the film use M-16A1 and AR-15 rifles which, in an effort to make them look more 'futuristic,' had their hand guards removed... which doesn't so much make them 'futuristic,' as it makes them impractical.
Then we got Escape From L.A., a story in which a 9.6 magnitude earthquake hits Los Angeles in the distant year of 2000, separating it from the mainland and flooding the San Fernando Valley. The United States has turned into a complete theocracy, exiling people to the now walled-off Los Angeles for committing moral sins (like drinking alcohol or eating red meat). And in the actually-still-the-future year 2013, Plissken is once again commissioned by the government to save the day, this time backed by enough 90's nostalgia to be considered a weapon of mass destruction. Why is Snake playing basketball? 'CAUSE IT'S AWESOME! Why is Snake hang gliding? 'CAUSE IT'S AWESOME! Why is Snake surfing? 'CAUSE IT'S AWESOME TO THE MAX, DUDE! Never mind that the computer generated effects for these sequences are so dated even by 1996 standards that they make the whole thing just that much more laughable.
Are they entertaining movies? Hell yes. Is Kurt Russell awesome? Hell yes. Am I thankful for Snake Plissken being the direct inspiration for Solid Snake and Big Boss? Without a doubt. But despite that, and despite my love for them, I have to admit... they've aged really, really bad.
