Even though I'm well out of the "kid" age group, lol, I do love me some good kid adventure movies — and of course books!
How do you feel about this list  that Fandango put together?
I love the Percy Jackson series and the first movie. It's one of those movies that I'll put on if I see it while scrolling through the channels, even though I've seen it a million times. The second book, Sea of Monsters, is my favorite. I can't wait to see the movie!
Holes is another one that I loved. You know, before Shia was big (but I loved him from Even Stevens). Most of them I've seen the movie but not read the book. And then there is, of course, Harry Potter. :) And The Secret Garden was one of my all-time favorite movies and made me read the book.
Do you think they did the books justice? If you have kids, would you let them read the book but not see the movie (or vice versa)? My son is not a reader, but my little girl is and I think that when the time comes, Johnny Depp's Charlie and the Chocolate Factory may be off her list until she's older. It's just too weird. I much prefer Willy Wonka and the Chocolate Factory. Gene Wilder is less creepy-weird, IMO. :) (And again, Harry Potter — the last movies are a bit much for some smaller kids.)
