Greta is certainly nothing unique. Person "A" takes a liking to a lonely, seemingly vulnerable person (Person "B"). The lonely, seemingly vulnerable person is actually a sociopath who has the ability to go full-blown crazy at the drop of a hat. And so they do, causing Person "A" to make a decision to either turn tail and run, or fight back. In Greta, Person "A" decides to fight back. We've seen this same premise before, multiple times. Sometimes it's in the form of a fatal attraction, like in Fatal Attraction. Sometimes it's in the form of a so-called friend going postal on the person that they're so-called friends with, like in Single White Female. The difference here between Greta and the two films I just mentioned is that the two fims I just mentioned are actually quite good films (Fatal Attraction being the best of the bunch). Now, that doesn't mean that Greta is a bad film. It's passable. The acting ranges from good to very good, there are a couple of genuinely creepy moments, and finally, the end is probably the best part of the movie. Indeed, I was about to come to IMDb to give the film a 5 out of 10. However, after I saw the conclusion, it was enough to bump my rating up to a 6 out of 10. That's not to say that it completely caught me off guard. But, it was done well enough that, even if it was somewhat predictable, it was still pretty satisfying. So, if you're watching Greta, and you feel like it's too familiar...too unoriginal, try and stick with it. Because the end is, in my opinion, the best part of the film.
