The Cheap Detective (1978)

It was purely coincidence that I grabbed another Neil Simon work after watching The Odd Couple II. This one has a similar issue that the schtick had really funny parts (it even had me comparing it somewhat to Clue), but when there were attempts at building a story, the whole thing feel apart and was just mind bogglingly confusing. The cast were quite dedicated to the parodies they were portraying with Peter Falk as the namesake detective and Louise Fletcher, Stockard Channing, Eileen Brennan, Ann-Margret, Madelyn Kahn, and Marsha Mason all playing different love interests.
