Look, you know me, and therefore you know I enjoyed this episode. Didn't *love* it - it's no Tooth And Claw or anything - but there was some fun dialogue, nicely farcical, and some great performances. I've read a few reviews which have said that THIS IS MEANT TO BE SCI-FI DAMMIT WHAT'S GOING ON I CAN'T COPE WAAAAAHHHHHH (or words to that effect), but hasn't Doctor Who *always* been more than sci-fi? One-off episodes like this are what makes it more than a niche show and turns it into something special and unique. Basically, you can read Marie's review to get an idea of how I felt about it!
On a related issue, Paul Fuzz has written a piece about critical responses to Doctor Who which should get us all talking :)
