“Renner” marks a return of sorts for actor Frankie Muniz. He’s been chipping away at an acting career over the last two decades, occasionally playing himself, but his new film puts him in a leading role for the first time in a long time, hired to carry a feature that attempts to expand his thespian range. Co-writer/director Robert Rippberger (“Those Who Walk Away,” “Strive”) joins a wave of storytellers looking to inspect the mysteries of artificial intelligence, and he lands on a drama about a young man and his computer-fu dealing with something he’s never encountered before: a woman’s interest. “Renner” is a glacially paced character study that eventually graduates to more physical interests, but Rippberger is in no hurry to get anywhere with the picture, overseeing a drab examination of an unraveling that’s way out of Muniz’s range.
