But it had David Tennent in it. How can it be bad if the Doctor is playing the bad guy.

The same way the Goblet of Fire movie was bland and average.

You can chalk up some of that to Rowling getting carried away with the book and opening up plotholes in an attempt to make her children's book grow up with her audience, but the movie was very much mediocre as well, despite having Tennant as one of the bad guys.
