Clearly patterned after the 2007 sleeper Wild Hogs, Old Dogs follows lifelong pals Charlie (John Travolta) and Dan (Robin Williams) as they attempt to cope with the unexpected arrival of Dan's two small children (Conner Rayburn's Zach and Ella Bleu Travolta's Emily) just as they're about to close a lucrative business deal. There's little doubt that Old Dogs, though suffused with an affable, easy-going vibe, strikes all the wrong notes virtually from the word go, as screenwriters David Diamond and David Weissman place an all-too-consistent emphasis on comedic set-pieces that simply aren't funny (ie Dan is trapped within the confines of a spray-tan machine, Charlie swallows the wrong pills and grins uncontrollably through a bereavement ceremony, etc). It's consequently not surprising to note that one's efforts at working up any enthusiasm for the central characters' ongoing exploits fall entirely flat, with the unreasonably cartoonish atmosphere perpetuated by an almost uniformly over-the-top array of performances (ie these aren't people; they're caricatures). Old Dogs' astonishing lack of laughs remains its biggest deficiency, however, and there's little doubt that the desperation that's been hard-wired into the proceedings is reflected in the progressively broad nature of the movie's jokes and gags. It's also worth noting that the presence of several familiar faces within cameo roles - Bernie Mac, Luis Guzman, and Justin Long, among others - only exacerbates the film's overstuffed, everything-and-the-kitchen-sink modus operandi, with the end result a hopelessly inept piece of work that's sure to turn off even ardent fans of the two stars.
