The imdb ratings here do not make this film justice. I believe that, like me, a lot of the viewers were intrigued by the promising beginning and severely disappointed by the really bad ending.
The story is about a group of strangers coming on a mysterious island where they are each promised to live their biggest fantasy. Here we get a sense of how confused were the makers of the movie: goofy comedy, akin to Scooby Doo, with dark and ominous hints, like a horror story, a distinct video game feel like the Jumanji reboots, but also the promise of emotional catharsis and a deeper lesson at the end. This could go in a variety of directions, some of them really good. Unfortunately the film continues to remain confused until the very beginning, where a completely artificial and nonsensical twist pretty much destroys every premise of the story.
Bottom line: the film was entertaining, the acting good, but the plot was a confused mess.
