“Top Five” is Chris Rock’s third pass in the director’s chair and first attempt at a more serious movie. It is a comedy, but relatively low key one for Saturday Night Live alums. It tells intertwined stories, both of which are well-worn. One is a straightforward romantic comedy about man having second thoughts about a pending wedding after meeting a much better match. The second is of an actor, Dre Allen (Rock), whose star is starting to fade a little, who is trying to stretch his career in a new direction, framed as an interview with a reporter. That the reporter (Rosario Dawson) happens to be the new potential love interest for Dre makes for a rather choppy narrative, but nonetheless one with many comedic highlights.
