In any event. . . I'm looking forward to Eragon. I've never read the books, myself -- but I always enjoy a good fantasy/medieval flick. And I don't even mind if it's cheesy. I mean, Conan the Barbarian was cheesy. BeastMaster was cheesy. Cheesy can be good. We'll see. At the very least, it should -look- pretty impressive, as it seems fantasy and historical movies are getting better budgets ever since LotR.
I read Eragon and am just about finished with Eldest. Considering the age of the author, it is amazing, but it is very Toliken derivative (though thankfully not plagiaristic such as the Sword of Sha Na Na). Or perhaps Tolkien meets Anne McCaffery. Anyway, it's reasonable entertaining.
Cheesy can go to far: Conan the Destroyer (the movie) was way too cheesy for me. No John Milius to save the movie from Dino De Laurentis. Beastmaster was too cheesy for me (and I think I'm the one who introduced the director of that to the Conan stories). The Conan books were cheesy, but not (in general) laughably cheesy. Loved those Frazetta covers.
