👍👍👍A massive THUMBS UP to the inclusion of multiple sub-genres on titles.

Of course, my day is not over until I make one complaint: While both are colloquial terms, whodunit (with 1 n) is much, much more widely used than whodunnit (with 2 ns) Additionally, the former form is especially widely used in the U.S. and IMDb generally defers to U.S. conventions in these matters.
