The result is “Bros,” one of the funniest, smartest, warmest and most enjoyable romantic comedies in recent years — a 21st century update of classic films of the genre from the 1980s and 1990s and 2000s, from “When Harry Met Sally …” to “You’ve Got Mail,” from “Notting Hill” to “Love, Actually,” from “Four Weddings and a Funeral” to “Jerry Maguire.”
