If you like Wally the series of the comedy movie "What we do in the Shadows" has an "energy vampire" straight out of Dilbert named Colin Robinson. The setting has moved from Wellington, New Zealand to Staten Island.
I don't know. I'm not into the vampire/monster thing. It never had any traction with me, so I'd have a hard time getting past the premise. But if they made a movie or TV series with Wally as the central character, I'd be there with popcorn.
