Season 4 of Teen Wolf (11 p.m., MTV) picks up far from Beacon Hills. The action moves to Mexico, where Scott is searching for a missing friend.This show isn't as good as it once was. It's still scary and surprising, but somewhere along the line it lost much of its sense of humor. It's not as much fun, but "Teen Wolf" is still watchable. Fans won't be disappointed.Elsewhere on TV ...World Cup soccer: Netherlands vs. Chile (10 a.m., ESPN); Australia vs. Spain (10 a.m., ESPN); Croatia vs. Mexico (2 p.m., ESPN); Cameroon vs. Brazil (2 p.m., ESPN2)The Bachelorette (7 p.m., ABC/Ch. 4): Six of the eight remaining bachelors have to take lie-detector tests ... because that's the way to find true love.Whose Line Is It Anyway?
