Re: Classic monsters return (spoilers)
I quite like that they're not baddies. The whole "Every alien race is out to destroy us!" vibe that the show had given off in the past gets old after awhile. Hell even Sarah Jane was a bit xenophobic as a result.
"The way I see it, every life is a pile of good things and bad things. The good things don't always soften the bad things. But vice versa, the bad things don't necessarily spoil the good things or make them unimportant."
