It's the first show to top the US ratings in its debut season since "Desperate Housewives," so obviously has something going for it...
I like it, but find it very "light" - the non-"Red John" episodes are a bit of a throwback to old-style hourlong standalone procedurals (i.e. no big story arcs), and there's as much focus on the banter between the CBI team as on solving the crimes. It's cute though, and Simon Baker obviously appeals to the ladies (Mrs Mickey makes no secret of it whatsoever!)
Worth seeing, just not a must-see for me just yet...
