“Nanny Surveillance” (** out of four) was an enervatingly derivative and predictable thriller about a yuppie couple ( Talya Carroll and Adam Huber) still reeling from a break-in who hire a nutjob nanny (Cinta Laura Kiehl) to watch over their family but soon find out she has watched “The Hand That Rocks The Cradle” a few too many times and is bent on destroying them and destroying their home. Not bad for this kind of movie and relatively well-made and well-acted but you’ve seen all this before and better. Final showdown is especially weak and disappointing.
