First of all I love disturbing movies. But i never watch this kind of useless movie. When it starts the visuals are quite impressive, building characters and story. But when she decides to take that injection it looks like she’s gonna have 1 week in younger body and 1 week in her owns. And they just twisted it, and make the younger version totally a separate personality. I dont know what makes her to do that her life split into two without a good reason sharing her life with someone when she wants to live life with happiness.
Don’t watch this movies, So overrated.
