It's a colourful movie. A fun time. Strange at times. Nasty at times. A quick watch.
It's a 6, but don't get me wrong, I enjoyed it. Wouldn't recommend it for anyone as it's hard to explain this film without being judged. In a way, when I was explaining the plot of this movie to my friend, it felt like explaining and recommending a porno. So keep that in mind.
I liked the visual aspect, the sound design. Then you might ask, but why is it a 6, oh mighty commentator? Because of the themes. You see, my dear reader, this movie tries to be something more than just a NSFW movie - it's a coming of age story. "Avatar" level storytelling - nature=good, destroy=bad. Everything thematically is told to us by Helen. No need to figure any underlying story out - we're too dumb, so Helen (she's the protagonist) will tell us everything. It goes on for the majority of the movie, except until the very end, when Helen doesn't state upfront everything - but by then, the interest is gone. So is gone the further analyzing, as you can see through the plot clearly. No need to ponder even 5 minutes. Movie finishes and you come out knowing about the character and the plot and its themes more than the staff who worked on the film probably knew.
And it's a shame, because there certainly are interesting visuals, but when the movie's set up in a way that teaches its audience just to observe and not to think, you can't expect me to walk out and spend the rest of my night thinking about that scene, when Helen jumped into what appeared to be an empty pool. Did she die? But why was the story continuing? Was it the future?... There was no set up for that. You didn't teach me that. Most movies (the ones that want to make you think, at least) don't need to worry about that, because the story itself evolves in a way that rewards analyzation. In this film, the analysis is not needed - you're given all the answers without putting any work.
But I still enjoyed "Wetlands" as a fun, but secretive pre-sleep movie.
