May is over, so it's time for Peter Travers to toss the worst movies of the month into the Scum Bucket, the disgusting repository for Hollywood's foulest junk. Though Peter loved The Avengers and Moonrise Kingdom, pretty much everything else this past month has been horrible. In this segment, he crams Battleship, What to Expect When You're Expecting, Chernobyl Diaries, Dark Shadows, A Little Bit of Heaven and more into the bucket.
