I don't think it was very different from any number of Tennant or Smith episodes, and the little creature was quite on par as well. I liked it just fine.Just finally caught up with this episode and I guess I'm another anomaly as I really enjoyed it! Loved all the bizarre elements of it, especially the weird little creature. I'm turning into a big fan of all the teamwork and other characters being competent and having skills, and the Doctor being a guiding hand.
I think the first time we ever saw the sonic screwdriver was in a Patrick Troughton episode, "the Temple of the Cybermen" or something like that.I've probably missed something, like where it's used as a screwdriver
