Serkis is great but the film is
a familiar freak show of hardship and ego run amok: a mad man of a singer - songwriter who, physically crippled by childhood polio that left an arm and a leg emaciated and nearly useless, blasts his way to stardom with cheeky lyrics and a stage act heavy on theater, while off stage fails as a husband (to artist Olivia Williams, tired of his self - involved existence), father (to impressionable son Bill Milner) and boyfriend (to adoring Naomie Harris).
