I loved it. I only started listening to Amy’s music and seeing interviews on YouTube and a documentary on Amazon after she died. With only those references to go by I think Marisa played her fantastically and I enjoyed the rest of the cast too, Especially Eddie who played her dad. This film elicited a lot of emotion from me and I found myself wanting to protect her and feeling very sad we lost such a beautiful spirit. All you can do is see it for yourself. Amy literally marched to the beat of her own drum. Do the same, don’t let negative reviews replace your own experience.
PS: Marisa did all the singing in it.
