There are no weaknesses in this episode, none of the painful sentimentality that occasionally hurt the later seasons. The main plot deals with the madness of military organisation, which used to be typical for MASH. The search for a raunchy movie sets off a series of deals and compromises. You might even expect Sergeant Bilko to show up at one time.
Another plot line deals with something that has always bothered me about MASH. In my own, short military career (national service) I did witness alcohol abuse in the army, but I could never believe that doctors at a MASH unit would drink so much. The general's order to ban alcohol from the 4077th seemed logical.
