If you saw Shallow Hall you saw I Feel Pretty. Same premise. An unattractive person has something happen to them that changes their self-perception. Amy Schumer falls off her bike while exercising at Soulcycle (ton of product placement) and wakes up and sees herself as a beautiful model. She also thinks that’s the way everyone else sees her. Now she has self confidence and a great job to go along with her perceived good looks. Fast forward and she knocks her head again and everything is gone. She’s back to the way she always was.
Maybe there’s supposed to be a hidden lessen that we’re all beautiful on the inside but we just don’t see it. The movie was watchable and had some funny parts but wasn’t anything so special for me.
