I'm a guitar snob so this won't apply to your experience, necessarily. Saffron's acting was fine and good in this common 'oops, I'm dying, but I can deal with it via credit cards' story, but she couldn't play guitar, and worse, she had no body relationship with the instrument. Probably won't bother most folks but it kind of spoiled it for me.
The transformation of a woman after she is diagnosed with a terminal illness, fired from her thankless job and abandoned by her boyfriend. Given two months to live, she blows her savings and maxes out her credit cards to pursue her dreams, which include romance and learning to play the electric guitar.
