Trading in one baked good for that sugary, multilayered symbol of commitment, the wedding cake, the freewheeling "American Pie" crew reunites for one more round of debauchery. If you thought a wedding would temper the classic plot, consider the operative elements: Bachelor party. Sexy maid of honor who's not quite up for grabs. Alcohol-induced pre-ceremony confusion. And, as if one wedding weren't enough, there's a plot line involving Stifler's parents. If it's not quite "American Values" in action, well, these Pies never were -- except, maybe, for the way they managed to parlay goofy sex into worldwide grosses of more than half a billion dollars. That's enough to make a permutation like "American Divorce" seem less like a longshot than a reason to keep the bakery open. Meanwhile, keep an eye on that cake.
