Good times here, free of  angst and ultra-violence. Maybe even swears! (no promises about the last one). In “Welcome to Marwen”, Steve Carell plays a man who recovers from a trauma by creating a miniature world where he’s a war hero. In “Second Act”,  a box store worker (Jennifer Lopez) fakes a resume and gets hired  to handle a major business deal. “Mary Poppins Returns” finds the flying nanny (Emily Blunt) returning to help the grown-up Banks children with their new families. “Instant Family” has Mark Wahlberg trying his hand at comedy as a parent who takes on a trio of foster kids.  ‘Agatha Raisin” brings M.C Beaton’s humorous mystery series to the screen.
