Denpa Onna to Seishun Otoko and Bakemonogatari contain the same elements of comedy, animation, scenery and over all feel. The scene transitions and cuts are almost exactly the same. The main male characters are extremely similar and the main female characters both have a unique and different personality that make them awesome. Both are made by the studio Shaft and directed by the same director which therefore makes the two even more similar. The only difference would be the plot. However, I believe the relationship/humor/combination of the two leads make these two animes go well together.
