I don't think it's cause you're old; if a long-standing action series I loved had a major title become turn-based, I'd be a bit miffed as well. It's just a matter of preference, and again I understand that, I just happen to be on the side that benefits.
And it's funny you mention the remakes of Star Wars as opposed to the prequels, cause with the prequels, you can just avoid them, but if you didn't get the right VHS copy of whatever Lucas stayed the hell away from, you don't get that many options when it comes to the altered originals, do you? I agree with the director of The People vs. George Lucas, the original cuts deserve to be maintained, and people should have access to them. And I'm not even a huge Star Wars fan, though I enjoy them.
LotR is an interesting one; what I've read of Fellowship seems fairly similar, but I know there's about a million more characters and plot threads than in the movies. There's a Nostalgia Chick series of reviews that mentions a lot of that. Me personally, I casually enjoyed the trilogy, but the only Tolkien book I've actually finished is Hobbit. Saw the movie too, and a bit annoyed Jackson didn't just make it one movie, but I enjoyed that as well, despite the criticism, though I enjoyed the book a lot more. It was assigned in 8th grade, and I've also seen the 70s cartoon of it. lol
I'm surprised you didn't mention Star Trek, but I guess we've been through that already. I watched "Space Seed" and had seen Wrath of Kahn before this new movie, and I enjoyed all of them, old and new.
