Yeah, the latest Doctor Who. The one with all the trees.
Every attempt to inject sciencey content was completely wrong from beginning to end.
Monster CME is big enough to blow the whole planet away! But, adding some oxygen to the atmosphere will make everything fine. WTF?
Trees control the supply of oxygen, ergo, you can't set fire to one without its consent. WTF?
There were several more, which have mercifully faded from my memory overnight.
Oh, and that CME was in remarkably tight focus when it arrived. A tiny fraction of a degree off in either axis, a tiny fraction of a second off in arrival time, and it would have missed the planet completely. Had to be carefully planned and guided. Only the Ringworld meteor defense is so precise*.
Oh, yes. There was a tyger. It wasn't burning, though there was a certain amount of brightness involved. Pity the brightness wasn't among the writers.
* Actually, it's nowhere near that precise, but I couldn't resist the temptation to rephrase my original sentence there.
