Did anybody ever watch the big budget live action film they did ages back?
If not, try and imagine loving something as a child, then seeing everything you enjoyed about it changed, ruined, removed or just wrong. Only thing it had going for it was confusing my penis into thinking I would shag Lady Penelope. I'll fetch you your Rolls you dirty posh girl...
I actually grew up watching it, being very much of that generation of kids who caught the reruns in the 90s. I didn't quite realise what was off about it at the time, and admittedly ended up focusing on the visuals because hotdamn those redesigns were actually pretty great. The film at least understood the sense of the overly grandiose stock footage.
Been a while since I watched the new series, and while it was awkward in places, I did it find it well done in points as well. Again, mostly visuals - one sequence that sticks out to me is when Alan is goes on a spacewalk (long story, Thunderbird 5 got taken over by an AI) and there's some really cool tracking shots with the camera because it's all in space and so there's no real up or down, so it follows his path as he shifts orientation.
Honestly though part of what's made being a fan of the show interesting is slowly coming to understand its influence on another culture and its entertainment - specifically Japan's, and the development of mecha tropes. Mazinger Z rising from the swimming pool? Lifted from Thunderbird 1's launch sequence. Super Sentai (and thus, Power Rangers) took a lot of damned notes from Thunderbirds in realising how miniatures could be used to depict machines of a massive scale, and GoGoV (and thus, Lightspeed Rescue) in particular is a full on homage, with the show being rescue themed and centred around a single family of heroes, in the sentai version anyway. Seriously, look at
this, and it's not hard to spot the DNA of Thunderbird 2 in there. Really, if you see some overly long and detailed launch sequence in a Japanese work of fiction that both pads for time
and looks cool, you can thank Thunderbirds for that. Shoji Kawamori - of Macross fame - even repaid the favour by designing Thunderbird Shadow for the new show.
The legacy it has is honestly astonishing.
