I think I'm most upset...
that they missed out the scene where Yossarian is in hospital because of the wound to his thigh with Dunbar. In my opinion it's the funniest part of the book.
Really I wanted to see Yossarian to tell Nurse Cramer to "screw" and for Nurse Duckett to take him to bed by his ear, and for the fish dreams, but most of all for Major Sanderson to be there asking Yossarian if he's man enough to take it and Yossarian replying:
"God no! I'll go right to pieces."
They really should've included that line.
