After a promising first hour, Five Days deteriorates into a soap opera that seems to willfully defy credibility. Overacting abounds, with Penelope Wilton winning top (bottom?) honors.. Hugh Bonneville and Edward Woodward are wasted; David Oyelowo's character must be the Worst Grieving Husband in the history of television. Rarely has so much skill at production been held hostage to such a disastrous screenplay (one that revels in irrelevant subplots). Three stars for the first hour-which is quite good-but otherwise...ugh. Anyone who can figure out the purpose of Sarah Smart's character can drop me a line and explain it.
