Coisa Ruim is, indeed, a movie that makes us believe that the Portuguese film industry is finally reaching for the audience, without compromising the quality of their productions.
I think enough was said here about this movie's main theme and plot, so I'll just emphasize (in my opinion) its main positive/negative aspects:
+ acting was well above average + beautiful photography and careful set selection + simple interesting plot understandable by all (not like most Portuguese movies)
- over-articulated dialogs, sometimes people seem to talk like if they all add degrees - too much usage of focus/defocus effects (it becomes a bit boring...) - over-saturation of the image, sometimes you can tell it was really sunny when the scene was shot, but in order to maintain the dark tone in the movie you get over-saturated colors and too much contrast
All in all, a good movie. A promising debut for this two directors, and a new breath for Portuguese movies.
