How drama-oriented is Monster of the Week?

I think the title is a clear-enough statement of the question, but essentially: is MotW a serious, drama-oriented game like Monsterhearts, or more of a comedy-adventure game, or a Twilight Zone sort of thing, or what? Basically, what's the default tone of the game?

Thanks in advance for any feedback and insight.

My intention as a designer was to have the tone of Supernatural and Buffy, but leave it open to each group. It can stretch from Scooby Doo style or straight horror if you want to.

Gotcha. Thanks for the reply.
