Dreary beyond measure. I didn't care about the victims and the plotting was convoluted. It also included the characters being able to access information they couldn't possible have done, even with the 'connections' they conveniently had.
The portrayal of the Coopers Chase Community was well drawn and there were a few smiles as he fondly explored the old people's ability to cope with the digital age. It also reminded you that though they might seem sweet and helpless you shouldn't underestimate an elderly person solely on the basis of age.
Overall, I would say give it a miss.
