Despite the miserable selection of films from last Friday, this weekend’s releases offer something for everybody including a scary children’s flick (“Monster House“), a fantasy thriller (“Lady in the Water“), a superhero cheesefest (“My Super Ex-Girlfriend“) and a scabrous comedy (“Clerks 2“). Of course, while all of these films seem poised to take home top honors after opening weekend, there’s still the big bad “Pirates” sequel to worry about. Will Johnny Depp and Co. win first place for a third week in a row, or can one of the four new films finally bump the swashbuckling actioneer off its throne?
