There were a few times while watching Jellyfish that I thought I would have to turn it off. While my own childhood experience was not as extreme as the ones seen in this film, it was close enough to make watching it quite difficult. At the same time it was so good in its performances and the intensity of emotion that I was practically compelled to keep watching. I kept thinking, the ending of this film better be damn good as that will be what makes watching it ultimately worthwhile. In this context I found the ending to be a disappointment though not inappropriate. The story of the eldest daughter of a mentally ill/narcissistic drug addict mother, and how the daughter works so hard to keep the family, including much younger twin siblings, intact and the toll this takes on her. At the same time her emotional struggles lead her to write comedy, so there is something of a silver lining. I would recommend viewing it if you desire an emotionally intense movie-watching experience which includes some nice shots of one of England's quaint seaside towns.
