That couldn't be much further at odds with its TV ancestor. I only ever watched the show occasionally because it was light on the supernatural and long on gothic soap opera. It sure didn't have any comedy. This movie looks more like a re-skinned Munsters, or maybe Addams Family if it's lucky.
Still, looks like it might potentially be amusing on its own merits.
I seem to remember some occasional quirky humor along the lines of, say, the Avengers, but it certainly wasn't known for it.
