Looking at the Wikipedia article it is made clear that Mr Anderson (RIP) did not approve of Thunderbirds (2004):
"It was disgraceful that such a huge amount of money was spent with people who had no idea what Thunderbirds was about and what made it tick."
He also said that it was "the biggest load of crap I have ever seen in my entire life."
Now as a dedicated Thunderbirds fan myself I quite enjoyed the film and thought it was reasonably accurate (although there were certain aspects that the writers took some creative license with such as the creation of Fermat or a wife for Kyrano). Sylvia Anderson also was reasonably pleased with the film (see the Wikipedia article).
My question is what aspects of the film did Mr Anderson (RIP) not approve of? I'm looking for quotes that actually explain this.
