I thought it was a wonderful start to the series - funny, confident, and with a clear direction that they're heading in. Not to mention that surprise as well...
I understand this year's connecting factors are twofold - an Agatha Christie book title being hidden in each episode's dialogue, and something from each episode will end up in the finale. "Partners In Crime" was fairly obvious for the Agatha Christie ref, but the bees reference is certainly puzzling me for the finale.
Solid 8/10 for me, and only not a 9 because I think they'll get better yet.

Random DW stuff update.
Episode 9 (the second part of Stephen Moffat's two parter) has had its name changed from River Run to Forest of the Dead.
And looks like the time slot will be slipping back to around 7pm again around episodes 5 or 6. Given even David Tennant and Catherine Tate expressed surprise at the time slot on Friday Night With Jonathan Ross, to add to RTD's stated objections, not a real surprise. :)
