Interesting to see the meteor fall to earth (which I don't believe we get in Tooth and Claw itself), just a nice little addition.

The scene of the man running away from the werewolf is a little confusing in terms of how it fits into the actual episode though. If it weren't 300 years later, and were an event taking place years and years before, that'd be fine, but being where it is is strange, is the wolf not with the monks at this point?

The actor himself does a great job, and historical costuming is always a strong point for the BBC, so I'll grant them that, but showing the werewolf as well is a major mistake for what's meant to be a teaser for the episode. Also it appears to be the middle of the day, which doesn't make much sense for the werewolf.

And we are already at a Low..

This one is just a lot of Nothing, if it wasn't for the overused Stock Sound Scream, then it would be pretty unmemorable. As an Idea, seeing a bit of the Werewolf from that Episode is fun, and the Idea of the Scene itself with it hunting somebody is great. But I cannot take it seriously because there is no possible Tension to be felt here. Neither the Music nor the Directing make it any tense.

Good Idea, poor Execution.
