So you're desperate to see that movie everybody's talking about, the one where the naked guy does pig noises while the girl underneath him in the bed prays to the Virgin Mary and makes like pinwheels with her eyes? Oscar-winning performances all around, of course, but not exactly family fare. What do you do with Junior while all of this is going on? Muvico Theaters, with multiplexes in Pompano Beach, Boca Raton, and Davie, has a civilized solution. They have children's playrooms where, for a modest fee, trained child-care specialists will watch your kids, aged 3 to 8, while you're satisfying your aesthetic needs. Junior gets crayons, games, a computer zone, a reading corner, and a chance to see free movies in which the pigs act not like farmyard beasts but like kids. They'll even equip you with a beeper so that, if Junior flames out over the lame entertainment menu, you can be summoned to try to set things right. The service is available Fridays through Sundays, 5 to 10 p.m., and it costs $5. Get there early; slots are available on a first-come, first-served basis. The service is also available at Muvico's Palace 20 in Boca Raton and Paradise 24 in Davie.
