Sarah (Lane), the film's centerpiece, is fortyish, recently divorced, and, of course, cringing at the prospect of getting back into the dating game. The body of the film is all about Sarah, surrounded by assorted kith and kin, struggling to cope with the difficult process of finding Mr. Right. A light hearted romp which is just a new take on an old but tried and true premise, "Must Love Dogs" avoids the extremes of edginess, quirkiness, schmaltz, and corn and concentrates on just being a pleasant up-beat ride to a foregone conclusion. Hard not to like but not likely to be memorable, this little bit of fluff got respectable though nominal marks from IMDb.com's voters including an average score from that hardest of all demographics to please, the 30-44 age of disillusionment group. "Must Love Dogs" should play well with females and their significant others, Lane and Cusak fans, and anyone in the mood for a low cal romcom DVD watch. (B)
