(展开全部) A few years before he went on to make a big splash in the cannibal sub-genre, Ruggero Deodato directed this successful rip-off of Roman Polanski's brilliant Knife in the Water. Naturally, being an Italian film - there's more of a focus on sex than the relationship between the central couples, but the claustrophobic atmosphere and entertaining characters help to keep the tension bubbling over, which ensures that the movie is interesting for the duration. The film doesn't have nearly as much 'bite' as Cannibal Holocaust and most of the rest of Ruggero Deodato's filmography, but it's obvious that even with this early film; Deodato is a director with the potential to make a mark on cinema. The plot is simple in that it just focuses on two couples. George and Silvia invite Irem and Barbara for a weekend cruise on their yacht. It soon transpires that George isn't the most sensitive man to ever live, and Silvia doesn't seem to mind him treating her badly. The situation escalates, and Irem and Barbara join forces with Silvia for vengeance against George...and three way sex, of course.
可惜角色塑造流于表面，过于脸谱化，好人一味善良、坏人纯然邪恶，缺失深度挖掘，难以给人留下深刻印象。
情节老套是这部影片硬伤，观影不久便能猜中后续走向，如同嚼蜡般缺乏惊喜，难以勾起深入探究欲望。
部分情节的发展较为平淡无奇，但整体上并不影响观影感受。
观影全程如坐针毡，冗长拖沓、乏味剧情，加上糟糕视觉听觉呈现，既无娱乐价值，更谈不上艺术熏陶。
特效场面令人叹为观止，每一帧画面都如同艺术品般精致。
