Personally, I thought the Toclafane descending en masse to "Voodoo Child" by Rogue Traders was in a way, kinda haunting - such an upbeat song when a tenth of the world's population are being killed.
As for the Master himself, okay, yeah, I'd say he was a bit too unhinged. Remember, though, he saw battle himself in the Time War, even seeing the Dalek Emperor capture the Cruciform (obviously Not A Good Thing), and he legged it, re-wrote his DNA, became the Master once again after who-knows-how-long, gets shot and regenerates (not to mention the implied madness of staring into the Time Vortex when he was young). But despite the jokes, he's still dangerous.
I'm wondering who the Toclafane really are. I have a theory, certainly, but I wonder if they'll end up like the Beast - never knowing who they really are? Oh, and I did like Cloudbase - sorry, the Valiant.
