I don't mind thrillers that do build up and make you think(aka psychological thrillers) but this was bad. There basically 2 parallel stories in this movie told from the perspective of 2 women with the same exact friends and married to the same guy but something just seems off.
Sounds like a decent enough premise right? You could go anywhere here and pull the rug out from under the audience and dun dun dun, one of them is the "real" woman and the other is an imposter who is deluded into thinking the fantasy in her head is the truth. Right there, that already sounds miles better than what happened here!
Instead they show the 2 women's perspectives, drop subtle red herrings, a cat fight ensues and an ambiguous ending closes it out. We don't know if both women were somehow living out their fantasies with the same guy as their husband and the same friends and the desire to have a child of their own but this just wasn't executed well at all. Fine, neither is the real Slim Shady so to speak, but give us more to the ending...
What seems like happened is that someone or multiple people wrote 2 different stories halfway and mashed them up into this mess and tacked on an ending that they can say is thought provoking. Nope, not this time. All we got here is 2 incomplete stories that were half told that turned into a movie that looks like it ran out of ideas and money.
If this wasn't a thriller, I would've walked out halfway but I wanted to see how it all played out. This was a very limp thriller that wanted to be clever but just didn't execute properly. Save your time and money.
