The acting is terrible, but I would blame for that mainly the director skills. Well, a director has to do several stuff besides guidance of acting performance, and I think other work isn't that bad. The genre is more than clear and the art coherent, the mise-en-scene is sometimes too predictable (mainly the shots), and the dialogs are funny, not that overdone like the acting.
This is a film where the people did a lot of things, the main actors wrote and produced, other staff is in secondary roles, so it seems like a heart-project.
If you can live with overacting, it is a interesting homage to Film-Noir.
PD1: Thinking about it, maybe the overacting (also overstatement of mise en scene with details like CloseUps, tear on cheek, etc) is on purpose, there is people who like it (Jim Carrey, overacts in most of the films, but he can also, as he has shown sometimes, act in another style). Well, in that case, it isn't lack of skills, it's just a style I don't enjoy.
PD2: Funny is also so much people taking negative comments personally, accusing of trolling, manipulation, and other conspiracies. 'common, everybody is free to have an own opinion, and everybody shall decide what to take from them.
