“Sausage Party” is something far short of Shavian in terms of sophisticated dialogue - really, there is just so much novelty value one can milk from repetitious fusillades of F-bombs launched by animated characters - but it is difficult to deny the hilarity quotient of a movie so exuberantly and unapologetically rude and crude. But the happy couple’s great expectations are upended by a shopping-cart collision that triggers a long after-shopping-hours journey toward rude awakenings, inconvenient truths and, during an extended climax, what very likely is the first food-on-food polysexual orgy in film history. Frank (voiced by Rogen), the most outspoken of the links in a package of sausages, eagerly awaits the happy day when he can nestle inside a sexy hot-dog bun ( Kristen Wiig) and, ahem, cut the mustard.
