Kill Bill, hmm, now that you mention it I wholeheartedly agree, matter of fact. Tarrantino himself started out making one film...and it started running longer and longer. It does drag in parts and seems to deviate. Part II, was better than I. Both good though.
Sometime some of my beloved anime movies I want to edit out the silly voices or the "he-he-he", "whhhaaaaaaa" (like Moe from the simpsons, in anime it gets used ALOT) and "huh" with extreme faces, they add really silly elements to what can be dark and intelligent movies like Ghost in the Shell or Vampire Hunter D.
