Almost the opposite of Horror and dark humour, I class anything that is very light-hearted in nature as Whacky.

Light-hearted stories often don't take much mental effort to read, and often let their characters go "out of character" for jokes. However there is only so far a reader's suspension of disbelief can be pushed before a comic starts to feel like they make no sense.

Whacky Comics tend to avoid being pinned down and will often cross into other genres as they see fit, so if I class a Comic as Whacky then expect to see a lot of the other genres appearing briefly.
