My only real exposure to the Thunderbirds was through a book I got as a kid from a second hand store. Heck, I might still have it around somwhere. I was very happily surprised though when I saw the Thunderbirds movie trailer. Not only did everything look just like I remembered it, but even some brief glimpses of some scenes tweaked things deep in my memories.
The movie itself looks very disney-esque, like spy-kids, not the adult version of the kids series, but who knows, it might not suck!
