One example from recent memory is the universally-ignored 2015 remake of the Chevy Chase classic National Lampoon's Vacation. Seeing as how this is far and away the best and most beloved film in the National Lampoon arsenal, I get why people weren't in any hurry to see it remade. But at the same time, "best National Lampoon movie" isn't that great of an accomplishment when you look at the competition in that field. Yes, Animal House was great, and Christmas Vacation is one of the best straightforward Christmas movies ever made, but there's a lot of garbage in the running beyond those well-known titles.
You've seen almost none of these movies.
Stop being so goddamn precious about National Lampoon movies, is what I'm saying -- if for no other reason than you're selling yourself incredibly short by having never seen the surprisingly hilarious remake of Vacation. It stars Ed Helms, and instead of acting as this generation's Chevy Chase, he plays the role of Rusty, the son in the original film.
The story itself isn't remarkably different. It's still about a family trying to get from point A to point B on a cross-country road trip to an amusement park. It's not a groundbreaking plot by any stretch of the imagination. The ending is no more or less believable in either film. For both, it's the jokes that do all the heavy lifting, and the jokes in the remake are, I'd argue, every bit as strong as those in the original.
