Michael, who is excellently portrayed by John Travolta, is an unorthodox Archangel enjoying his last mission (vacation?) to Earth. A supermarket tabloid from Chicago sends a team to Iowa to get a story and pictures; after discovering that he's a real angel they naturally want to bring him back to the big city.
What works best is that the story is essentially a fun-spirited road movie (I'm a sucker for road movies). William Hurt, Andie MacDowell and Robert Patorelli have an exceptional time meeting Michael and trying to escort him back to Chicago. Michael acts like a tourist having the time of his life, humorously wanting to see those silly little attractions we see dispersed across the countryside (e.g. "the world's biggest non-stick frying pan," etc.) -- you know, the ones most of us adults roll our eyes at.
Lots of fun things and miricles take place along the way (e.g. women are naturally attracted to Michael, bar fight, bull fight, etc.); you should discover them for yourself when watching the film. What struck me the most about Michael is that he had a true spirit of joy. The simple joy-of-living-itself was all over him; and this naturally had a big impact on all the people around him. This is something most of us could learn from Michael.
I was pleasantly surprised -- "Michael" is fun, charming and delightful -- not just another run-of-the-mill "chick flick" (in other words, guys will enjoy it too). Recommended.
