I've just finishing the second season of the show and honestly I can't say that the change are good. The first season was very great, something different about a profiler who are an "empath" who investigate murder done or not by serial killer. The dark side of the serie was balanced by Frank familly life (the little girl remind me a lot of my niece who are 5 years old).
But on the second season James Wong and Glen Morgan are responsible for the series in place of Chris Carter who was occupied by the X-Files movie. Suddenly the dark athmosphere of the show is not really there, the Millenium group take the first place and Millenium had became a X-Files conspiracy show about angels, demons and catholic prophecy. For the first time a lot of ridicule episode (Jose Chung, Goodbye Charlie, Luminary, Siren, In Arcadia Ego and Somehow, Satan Got Behind Me) are includes and only one episode (The Mikado) looks like what the series was about.
I really hope that the third will be better, since it's what I will listen this weekend.
