Boomers familiar with California Wine Country & classic rock soundtrack of mid-70's will enjoy this flick. Timely soundtrack contains 4 Doobie Bros. contribs including appropriate & obscure "Spirit". Also noted is "Listen to the Music ", "Toulouse Street", and "China Grove". Perhaps no coincidence that the Bros. originated in nearby San Jose, CA, & long-time manager is Bruce Cohn of noted B.R. Cohn Winery of Sonoma. Professor Snape in role of Brit Wine Snob is bonus casting gem - nudge-nudge, wink-wink, say no more! Unfortunately, it will be difficult for this fine movie to harvest commercial success it deserves due to niche theme & lack of action/special effects that mindless public demands.
