It seems the Evil is not really all that Evil. This is another mining episode-- 30,000 years in the future, the Sun is running out of power and on a world at the very edge of explored space, several galaxies away from Earth, they find these colorchanging crystals that happen to be the vagues antimatter ever, and six pounds of it will power the sun for centuries, making the planet basically inexhaustable.
The Tardis goes off course a little, and materializes here, and of course, the locals think they're spies, that they're responsible for the deaths of everyone (one at a time, because there's only the one dessicated corpse in the prop vault), and that they're trying to ruin everything. Much talking ensues, and I kept losing interest-- this is one of the episodes that has long recaps and alot of escaping and recapturing, which we haven't had to deal with in a while.
Sarah Jane is particularly feisty and doesn't have to twist her ankle at all, but also doesn't get to do anything much but stand around with people in silly uniforms holding onto her arms. The Doctor is extra weird, but what's really strange is how... intense and non-silly he is. Like a flash forward to Six or something. The Captain is a jerk whose name sounds like Saladbar, the second in command keeps going along with him entirely and then disagreeing at the last second, and really there isn't much for anyone to do but yell and not agree with eachother. Oh, and there's a monster made of antienergy that's the actual killer-- and doesn't get enough of the story to matter. It is, however, a great use of the weird way blue screen makes things semi-see-through. And there's the scientist who was the last survivor of the survey team, the one who came up with the plan to steal the antimatter, who keeps drinking it and turns into a werewolf.
So, yeah, not that great.
In the end, the Doctor figures out that all the antimatter has to go back to the planet (that looks like a meatball) or it'll never let them leave, and he runs around risking his life to do that. He frees the scientist and makes him think he came up with a better plan while he's confused enough to be open to it, and they all live happily ever after. Or something.
