Bad boy Britpop singing sensation Robbie Williams has been such a party animal through much of his adulthood, it’s no wonder director Michael Gracey takes the wild swing of rendering his character as an anthropomorphic allegorical ape for the biopic Better Man (C+). And the ups and downs of fame, self-loathing and addiction prove it’s hard out here for a chimp, even if behind his big hairy audacious goals of showbiz superstardom, he’s achieved oversized celebrity in the UK and cult admiration here in The States. The film shines in big production numbers scored to such hits as “Rock DJ,” “Angels,” and “The One” with clever, kinetic choreographed sequences punctuating lesser passages. Behind-the-music style beats comprising much of the bloated story don’t shed much light on the interior life of the simian songster played with CGI motion capture by Jonno Davies. Rise to fame, romance, rap sheets, rehabilitation, reconciliation and more are on display, along with tiresome hallucinogenic alter egos laced through concert crowds to cast doubt. The film’s occasionally meta presentation wins points with wry, often profane quips but reveals very little about what motivates the character at its center. After a long time in the wilderness hibernation of what can only seem like Cocaine Bear has invaded Pink Floyd’s hotel room, there’s some tidy and redemptive sentiment to cleanse the palette. More cautionary mental health tale than rhythmic romp (a far less fun Rocket Man?), this murky movie monkey business wears out its welcome.
