Both have realistic take on the theme of pursuing one's dream. SUFBB is more youthful while Spark is more bleak.

Quirky characters, creepy cases, similar off-beat and dark atmosphere. Both also have male x female duo with great chemistry

Both are collection of creepy, dark, inter-linked stories about traumatized, defected people. Both have a theme revolving around guilt.

Similar era (Japanese occupation), different background (Korean and Chinese). Both have double agents and action, but nobody's wearing a mask in The Disguiser though

Both have similar set of actors and actresses. Nothing else beside that, but both are good in their respective genre

Both leads (the protagonist in NiF, the antagonist in Devil) use their enemy's dirty secrets and past deeds as their weapon to bring said enemy down while not actually doing anything besides setting the stage, thus not dirtying their own hand directly.

Only in The Devil the lead did what he did for pure revenge, while in NiF the lead did it to clean his family's name.

Both have some little narration here and there by the protagonist. Have similar style of humor and the characters are flawed yet lovable.

Lady Joker is a loose sequel of Marks no Yama. Both are short, dense, thrilling drama with great acting and brilliant writing

Same main actress, same writer, both deal with the aftermath of an important person's death

Similar era (gangster and politician join hand in hand, the importance of constructor), very similar background music (was it even the same?), similar style of presentation, lastly they tackle similar theme (injustice, rich people do bad things because they're bad while poor people do bad things because they have to) in a similar way
