Terrible acting. The characters lack depth except the protagonists. Most acting is boring and two dimensional. Too much unrealistic drama. For example, when Nolan is being attacked by another man, the woman who is with Nolan knocks out the attacker with a gun. The worst part is how police suddenly show up. How did they know? Even worse is how two LEOs rush in, as if they know exactly where to go and who to look for. Then they fire off shots as the two people get away. I doubt that this was ever police protocol. A LEO especially does not fire away at a criminal as the criminal is running away at a distance. It's more of a cute movie with corny one-liners here and there. It's supposed to be a mystery detective comedy I guess but it's just poorly made. There are plenty of early 1940s films like Penny Serenade that have depth and three-dimensional characters.
