Here, we have the golden years’ version of The Hangover: Four friends head to Vegas for a bachelor party; this time, the groom is 70. So far, so good. No doubt four lifelong buddies heading out to Sin City would provide a seamless vein of comedy to mine, one would think.

Billy (Michael Douglas), after decades of seeming bachelor bliss, is finally tying the knot with a girl young enough to be his granddaughter. Nonetheless, his three childhood pals from the old neighborhood are determined to make the most of it. Archie (Morgan Freeman) sneaks away from the watchful eye of his son; Sam (Kevin Kline) escapes the self-imposed hell of Florida retirement; and Paddy (Robert De Niro) is dragged from his widower’s grief to celebrate. Of course, with all life-long friendships, there are complexities; and a beautiful age-appropriate chanteuse, Diana (Mary Steenburgen), brings some painful reminders to the reunion.

The movie is fine. It’s funny, but not hilarious. It’s touching, but not poignant. It’s well-acted, but not brilliantly so. Oh, and there will probably be a sequel, provided the box-office return can cover the salaries of the talented cast. That’s it. It’s a 6.
