The Bradys nearly overdose on Hollywood high concept in this try-too-hard sequel, which introduces Mom Brady’s long-lost first husband (Tim Matheson) and throws in a scheme to steal a priceless family antique. Where the first Brady movie’s brilliantly retro sitcom style made it a natural for home viewing, director Arlene Sanford’s more broadly pitched follow-up isn’t such a perfect fit. With its overtweaked plot and gimmicky guests, A Very Brady Sequel is too reminiscent of other movies made from TV shows. Yet there are still real laughs to be had from watching this stuck-in-the-’70s family trample obliviously through the cynical ’90s, while the filmmakers maintain their much nimbler footing between celebration and send-up.
