The Plan Man

Both lead in both movies has Obsessive Compulsive disorder. It looks funny but it was hard for the person in real life to fit in the society. Really fun watch

Both movie has a main lead that has OCD and met a woman that is opposite. Very funny indeed. Can he change? Or accommodate? Or be friend with the woman?

Both main male lead has the obsessive cleanliness behavior. It is hilarious. Can he tolerate the massive care free female lead behavior? Can his behavior changed?

With the same male lead, this movie offers the same amount of comedy. Great for overcoming any huge drama slump!

Seem to have a different vibe, are from different decades but the set up is kind of similar:
Main character has a specific quality they want to get rid off before confessing to their crush X. Helping them in their pursuit is another character (the actual Love Interest). During this, the characters grow closer.
