It's not funny. It's not engaging. It's not believable. It's not coherent. It's not logical. It makes no sense. It's badly acted, badly written and badly directed. I think you get the picture. This film is a disgrace, an unmitigated disaster. There's just nothing in it of any worth. No wonder La Cuadrilla disbanded and disappeared from view after this. A shame, given they had seemed promising when they began. (Update: they have resurfaced years later with the Spanish version of a French comedy show, which has been, inexplicably for me, an enormous hit).
What I hope is that nobody else ever sees this movie again. All copies of it should be burned, and the ashes dropped in a nuclear reactor for their complete evaporation, and the world would be a better place. You might think I'm being harsh, but that will only be if you haven't seen the thing. And believe me, you're much better off that way.
