Though not unlike a feature film in many respects, this succession of images, words, and music from goo-slinger extraordinaire Garry Marshall (Pretty Woman) is actually a finely tuned, demographically refined delivery system for the purest synthetic comedy substitutes Hollywood has to offer. A balanced blend of two dozen or so movie and TV stars (e.g., Ashton Kutcher, George Lopez, Julia Roberts, Eric Dane, Shirley MacLaine) democratically share screen time as Los Angelenos variously questing for love, dealing with heartbreak, or reaffirming long-term commitments. Valueless as entertainment, it’s still useful as a disambiguation tool for those who confuse Jessica Alba and Jessica Biel, or Taylor Dayne and Taylor Swift.
