Awesome Art: A necessity for a comic without words, Jim Woodring's lush drawings bring the hallucinatory dreamscape to life in vivid detail. Really, for sheer atmosphere and surrealism, it looks like no other comic ever drawn.
Critical Dissonance/Acclaimed Flop: While Frank has never seen large sales, it has nonetheless won critical acclaim and fan recognition.
Esoteric Happy Ending: Frank comes up with a brilliant song and reunites with his band, so he'll be alright, but Jon quit his job and spent his life savings trying to get the band up and running. Now he's parted ways with them and is broke in a foreign country. Even if he manages to get back to England, he'll still be unemployed.
Moment of Awesome: Frank's first appearance and his performance of the song The Ginger Crouton. After seeing Jon struggle to form lyrics well enough to write a whole song, it's quite refreshing to hear a series of random words sung by someone who clearly does not give a damn.
Unintentionally Unsympathetic: Poetic or not, the band's decision to cremate Don's remains is highly questionable. There is no indication that they have reported Don's death to the proper authorities, made an effort to locate his next of kin, found out what his own wishes were, etc. before going through with it.
