It isn't terrible, but it's just another mediocre TV movie in spite of the cast and story (the Poe story is ridiculous, but it's fun). The story lurches along until the last 15 minutes, when it falls flat on its face. The ending is abrupt, leaving major story threads flapping in the breeze, and the clumsy attempt to surprise the 1 in 100 viewers that hasn't heard the plot of the Poe story is very distracting. There is also a subplot involving a feud between the detective and the police commissioner that is totally unnecessary. Finally, the cinematography is occasionally muddy. On the plus side there is the good cast and the locations are very attractive, so it's tolerable.
