This movie can be summed up with 2 words. Why and No.
It genuinely should be the subject of a class action law suit for fraudulent theft of an hour plus of your life.
Portman's performance is appallingly bad. Self indulgent to the point of being a parody of awfulness.
Pick up your remote, click dislike and remove it permanently from your suggestions list. This will be considerably less painful than trying to excise it from your brain.
Unless of course you are a masochist who's enjoys insufferable pain. In which case fast forward to the last 20 minutes and watch a "concert" that manages the trifecta of bad staging, bad singing and bad dancing, with a tragic costume thrown in for garnish.
