This is a minor, inconsequential film, but it does have its charm.
It is supposed to deal with criminals and crimes, but in such a light way as to render it a parody of the genre. The criminals are all inept, the police more lucky than smart and naturally nothing works according to plan.
The performance enhances the parodic feeling of the film, with some overacting, but not in a jarring way. It's as if the actors had instructions to act in a look-how-stupid-we-are manner, and they do it brilliantly.
On the plus side, the film flies by rapidly. It has no real dull or dead moments, no introspection or philosophizing moral. It just aims to provide you with an hour and a half of good time, and in its minor, unassuming way, it does.
