“Grumpy Old Liv” provides many answers to the questions from the season one finale, while posing new challenges to the so-called “cure” Ravi mixed up. The case of the week centers on the death of an elderly man whose sour outlook on life rubbed everyone the wrong way. His racist remarks and hatred of everyone and everything around him didn’t make him the most liked neighbor on the block; however, it makes for very entertaining television when the cast of characters, including Det. Clive Babineaux (Malcolm Goodwin), must deal with Liv’s new less-than-sunny disposition.
