Jason Bateman and Ryan Reynolds in The Change-UpTHE CHANGE-UP

The Change-Up, in which Jason Bateman's discontented husband and father magically swaps bodies with Ryan Reynolds' perfectly contented slacker dumb-ass, is an appallingly smutty and juvenile slapstick. In the segment that finds Reynolds (in Bateman's body) preparing a late-night feeding for his pal's infant twins - with one tot seen playing with butcher knives and the other reaching into the blender and sticking his tongue into an electrical socket - it features one of the most painfully unfunny scenes in cinema history, and I'm not excluding any given scene in Sophie's Choice or Schindler's List.
