Nicky Ranieri's "Un tranquillo week end di terrore" is a disappointing entry in the Italian porn scene, falling flat with its uninspired plot and lackluster execution. The film fails to deliver on the promise of its genre, the "roughie," a subgenre that thrived in the '60s and '70s with its depiction of aggressive sexual fantasies.

The movie unfolds mostly on a yacht, where a group of thugs invade and hold the cast hostage, but their motives seem to be more about sex than money. The plot is paper-thin, and the non-ending is a letdown, leaving the minimal storyline unresolved.

The film stars Anita Dark, and Sylvia Laurent, among others. While the cast does their best with the material, the mechanical nature of the sex scenes fails to excite. A standout moment involves Laurent, who, with her expressive eyes and contorted face, conveys a range of emotions as she's taken by surprise, her pleasuring punctuated by fear and excitement. Her scene is a brief glimpse of what the film could have achieved with more attention to detail and performance.

Ranieri, known for more ambitious works like "LA FAMIGLIA" and "INSIDE GABRIELA DARI," seems to have phoned it in with this one, relying on the formulaic tropes of the genre without adding anything new or exciting.

In conclusion, "Un tranquillo week end di terrore" is a forgettable entry in the world of adult entertainment. It's a dull affair that fails to arouse or engage, a missed opportunity that will likely leave viewers feeling underwhelmed and reaching for the fast-forward button.
