IMHO some of the deleted scenes could have stayed deleted, however one that should have been left in was the scene in GFII when Michael finally takes his revenge on Fabrizzio.

I dont think the Genco death/hospital scene, or the Mike and Kay romping in bed scene were necessary.

I somewhat liked the scene in which Sonny's daughter and her fiance come to Michael to ask permission to marry. It showed a human side of Michael.
