Ever get stuck watching a movie and you couldn't wait until it ended? This was one of the few that I've seen. Excruciating is a good word. Only a great cast saves it from a lower rating - makes you wonder what they could have done with better material.
"Slightly Honorable" can't decide if it's a comedy or a mystery picture and fails on both levels - not funny and not very mysterious. Ruth Terry is 'cute and perky' but is an annoying presence. Eve Arden is wasted, as is Edward Arnold. Pat O'Brien does his best but it's not enough. The disjointed storyline is not believable and not worth recounting.
If this picture is shown on a rainy day and you have nothing to do, find a good book.
