Similar: The pacing of action. The use of color. The attitude of the main character. The main character: A bewildered male surrounded by a bunch of crazy chicks. Style. The psychotic little inserts, artfully translating the moodswings of the characters. I Love both.

The usage of word play courtesy of Shaft exists in both of these series. Both series tends to avoid a direct/linear storyline but rather have a slice-of-lifish theme that explores the identities of the characters. And of course with word plays means = random scenes with pictures depicting actions. Also, there is quite a large female cast in both series that has strange relationships with the main character. Comedy is highly present in both series.
