From all accounts, Steve Jobs was a brilliant innovator, but also a demanding, inconsiderate asshole. This biopic starts with his free-spirit college days, spends lots of time creating the first computer in his parents’ garage, then traces his rise and fall and rise at Apple. Ashton Kutcher, who is an on-screen charmer, is out of his league in this role, unable to plumb the characters’ complexities. Even though the screenplay tries to show Jobs’ good and bad sides, it’s just a flat, yet absorbing history lacking in emotion, drama or excitement.
