The Man From MI.5 attempts to break the usual Thunderbirds mold by providing us with a story of spies and subterfuge rather than flat out rescuing. Comparing this episode to a James Bond movie is nothing new, but while there are obvious links in the form of the Bondson character, he’s very much pushed off to the side and Penelope is at the centre of this story. This week, she’s the bold, cool, and slightly eccentric version of the character that we all prefer to remember rather than the whiny and a bit useless Penelope we saw last week. So is this her greatest adventure yet?
