This was a pretty intriguing movie from a psychological point of view and not at all boring. I at first thought it was going to be similar to "Don't worry Darling", after viewing the trailer. It's not.
At first, you can almost predict the plot but then start to change your mind. But your first instinct is correct. At least mine was. Is it perfect? Absolutely not.
Unfortunately for many of those, life isn't all roses and sunshine, and some people are just horrible human beings. My only qualm was it ended in a cliff hanger, and that's the most infuriating thing when watching a movie.
To sum this up, it's about a selfish woman who wants materalistic things regardless who she hurts. There's obviously much more, so give it a watch. Turn it off if it's not for you.
