Characters in the new Jennifer Aniston-Jason Bateman romcom "The Switch" talk a lot
about throwing one another a "curve ball." Ironic, since "The Switch" is about as down-the-middle as movies can get; so unimaginative and formula-driven is this movie that it seems entirely to have been hashed out by executives over a long lunch. And so limp and halting is its storytelling that we get the sense that we're watching only the rough cut.
