"The Black Cat" is definitely worth a watch! I was lucky enough to get Jeffrey Combs to sign my copy of the DVD at the Las Vegas Star Trek Con last year. He saw the insert, then asked if I was going to see "Nevermore" that night. I think I managed to reply yes, I was looking forward to it.
His performance was amazing. I was worried my attention would drift with a one man show, but he held my attention the entire time. Even my husband, who doesn't enjoy the language of the Poe era, liked the play. Liked. But he thought the performance was outstanding.
