It's funny how sometimes writing a review just comes easily, while other times it feels like pulling teeth—and this falls into the latter category, not because of any difficulty in describing what the film is or how it looks, but simply due to its overall lack of excitement and blandness. That’s really the feeling I'm left with after watching it. Now, that being said, it isn't a complete disaster, as Django does appear in it. Doesn't he always make things better? The story centers around two women, Kelly and Lucy, who accept an invitation from one of their former boyfriends to visit a paradise in Montenegro—a chance to relax, enjoy the scenery, and generally have a good time. It doesn’t take long to realize that Boban (Micanovic) still has feelings for Lucy (Burn), despite being recently married. This is all pretty standard stuff so far. What follows is an abundance of shirtless men, women displaying their bodies, and other unnecessary elements. Kelly (Klebe), meanwhile, harbors a fear of the ocean. Eventually, they encounter Boban’s friend Alex (Stefanovic), who provides some moments of levity. However, this stretches on for what feels like forever—nearly an hour—before anything significant actually happens beyond a couple of scenes involving fish hooks and murder. The character development is decent; however, the prolonged introduction, lasting over an hour, before the plot truly begins to unfold isn't so good. Spending that much time with people just fooling around and wearing swimsuits, no matter how attractive they are, doesn’t make for a compelling film. They ultimately decide to visit the small island of Mamula—the film’s original title—where things finally start to move forward. Overall, this isn't a particularly good movie; while the production values are acceptable considering the type of project it is, the script and drawn-out narrative really hold it back. The acting, however, is surprisingly strong from performers who have been in much better films, which makes you wonder how they were all convinced to participate. Apparently, Nero was difficult to persuade, but his presence certainly adds credibility and professionalism—though perhaps those resources would have been better spent elsewhere. Still, it’s Django, and he's always cool, so I can understand the desire to include him. The dialogue occasionally feels awkward, though that’s somewhat forgivable. The scenery is gorgeous; it truly showcases a beautiful part of the world. For a low-budget Serbian production, it surpasses expectations in most respects, with one significant exception: the killer mermaid herself. She has very limited screen time, but when she does appear, the special effects are quite impressive, despite some questionable CGI. Zorana Kostic Obradovic is both beautiful and captivating, and it’s a shame that more effort wasn't put into developing her character and building up to the finale—especially given that the film revolves around a mermaid. Mina Sablic deserves recognition for portraying the creature itself; the effects and makeup used on her are actually quite well done. Franco Nero is also reliably awesome, delivering a few memorable (albeit cheesy) monologues. It’s not the worst movie I've ever seen, far from it, but go in with modest expectations and you might find it entertaining enough for its length. I would recommend it primarily to fans of Nero and Obradovic.
