It's like seeing the original series, only with a modern sophisticated take on it. Even the score in the background despite being voiced over by the news reporter told you the bold, loud and proud direction that Thunderbirds will be going in. And considering that it's being composed by Ben & Nick Foster of Torch-wood and Doctor Who fame, I think it's fair to say that this will do it Justice.
Sylvia Anderson was very candid in that film-making for Thunderbirds had to progress, evolve and move with the times. I appreciate that the original series is heavily beloved and it has every right to be because I otherwise would not be taking such an interest in the new series if I were not a fan of Thunderbirds G1 or TG1, if you will.
What I like that Richard Taylor of WETA Workshop has done is Old-school meets new-school in using model sets by combining it with CG, which will make animating the characters and the Thunderbirds themselves a lot more plausible and have way more freedom than the limitations that they were bound by with strings in 1965.
As charming as the Marionettes were, you could never take them walking seriously. This will be a very different ball-game now as the Tracy Brothers will now be able to perform movements that were not even feasible with puppets with the original series. One small thing I hope not to see is bullet-time.
I'm probably worrying over nothing, but....you never know.
