Lie to Me is in serious need of plot and reduction of filler. The fact is, every episode begins with a small number of suspects and the pool quickly dwindles until Cal berates the criminal into telling the truth. Cal's tired antics just aren't cutting it any more. He walks with a swagger, gets in people's faces, yells, plays trick--every episode. There's rarely any deviation and frankly, it's old.
"Smoked" has the same setup and goes as expected. Cal first suspects one of the sons and goes around in circles, finding out information about them that isn't pertinent in the end. Then Cal moves onto the real criminal exposes him and that's that. The other characters, Gillian, Loker, Torres, look at him curiously but he gets the job done.
There were two long-term plot developments in the episode which I don't care about right now. Torres recruits a guy of the street, much like she was recruited from the airport, so we'll be seeing the excellent Michael B. Jordan a lot more. And Wallowski is probably Cal's girlfriend, although there's no full confirmation.
Score: 7.7/10
