Of all the movies he's done... which one should he be most proud of?

Kill Bill Vol. 2 for sure but how about something that isn’t a masterpiece like that movie is. Maybe something he had a more personnel role in making or getting made. I don’t know, just throwing it out there. I know I’ll be re-watching alot of his flicks now and maybe I’ll find one that he might have been most proud of eventually. But yeah, Kill Bill it is.
