First, the trailer (switch to 480p for better quality) for the episode:

Now, my concerns.

I freely admit that I absolutely hate James Corden and his partner in lesbian vampire fighting, Matthew Horne. Granted, Corden deserves kudos for his writing contribution to Gavin & Stacy, but I just don’t like the guy at all. Neither does Patrick Stewart, so it seems.

So far, this series of Doctor Who has been absolutely superb and I’m waiting with baited breath for the two-part finale. However, I really DO NOT WANT this episode, traditionally a ‘Doctor Lite’ affair during the Russell T. Davies era and now ‘Amy Lite’ (boo!) to lower the standards right before the big climax.

There is hope, however. A review posted over at Blogtor Who seems to suggest that the episode is really rather good, with plenty of laughs and creepy ending; I certainly hope that my pessimism is proved to be completely unjustified and perhaps, just perhaps Corden can begin to redeem himself in my eyes.
