Well, now that I think of it, we've gone through comedy. And sci-fi. And fantasy. Though, perhaps upcoming arcs can be more structured in those fashions, somehow.
Not to mention, horror, thriller, suspense/mystery, (not) Western, action/adventure, noir, etc, etc.
Eh, it may or may not work out. Just thought I'd throw the idea out there.
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
