|Not the vehicles, but it will do for now|
Thunderbirds only ran for two seasons, at which point Sir Lou Grade determined that he'd never get American network money to keep it going.
The charms of the show might seem elusive to some. For one thing, the main characters are wooden puppets which means that whether they are fighting to plug a volcano or bantering after a successful mission their expressions never change. And it's not exactly easy telling one of them from another. And the scripts are aimed squarely at kids, so subtlety and moral ambiguity are in short supply. Considering the first part of this paragraph, I'll say mercifully short supply.
However, Thunderbirds is a perfect example of art being improved by it's limitations. The miniatures are beautifully detailed and if they're a little unconvincing, so what? At least it's not more puppets! And while the puppets can't handle drama, the sweeping orchestral score by the late Barry Gray took care of that in spades. It all winds up being good fun once you get past the dodgy American accents and creepy feeling that one of the brothers looks a little too much like Cary Grant.
|Wait, these aren't vehicles either!|
What you're left with is this fun, wild implausibility. Who is paying for all this technology? And rocket fuel? And why, a century after it was fashionable, do the Tracys live in split-level mid-century Frank Lloyd Wright style ranch house with flagstone walls and conversation pit? In every episode they introduce at least one new vehicle or gadget or something that is so highly specialized that you would never, in the trial of a thousand lifetimes, expect to need it. And yet there it is, perfected and polished and working like a dream.
What I'm getting at is this is good, stupid fun and the episodes are only 22 minutes long so go ahead. You could do worse.
