I think that's a pretty condescending generalization about kids in general. You underestimate the savvy and flexibility of the youth.The kids these days have been exposed to Anime and MMORPGs or even just VideoGames whose genres are close to D&D. They werent in 1980. Sword bearing martial artists who perform periodic feats of wild and intricate action even ones who dont lapse strongly in to magic tropes.... are a part and parsel to a healthy amount of there fantastical environment.
Thinking "I hit it with a sword" is designed for them???? seems pretty head in the sand.
The LOTR they are used to involves an elf kiting on a borrowed shield into a super charge maneuver onto a battle and a warlord (ranger) flinging a dwarf impossibly far into position against a crew of baddies, and occasionally two arrows launched from a single nock.... not just the plodding counting of heads.
I grew up as a teen in the early 90s in a Third World Asian republic where most of my peers played Magic: The Gathering and Nintendo and had no experience of "I hit it with a sword," as well as any meaningful amount of experience with 1e/2e/3e D&D and I seem to have adjusted to it just fine thank you very much.
Also, while the combat powers of 4e are designed to reflect the over the top theatrics of today's fantasy such as "shield-kiting" and "dwarf-tossing," I've learned that many gamers with more experience and playtime than I have been fully capable of replicating this kind of dementedness without the 4e mechanics.
Saying that because kids grew up with a certain kind of fantasy (LOTR, anime, MMORPGs) means that they've received an education that closes them off to an entirely different style of play is like saying kids who grew up with comic books are incapable of learning how to read without pictures.
