I don't know what was the problem with this season but frankly, it's a disaster. Nothing is right: the new actress (why a 3rd change ???), the script, the other actors... Don't waste your time on this one!
A very successfull season with good rythm and a pleausible story.
Season 1 is OK, even if it's a bit slow and answers are given a bit far from the start... But wait for season 2, far better !
By far the best season since the start of this show. Finally! Definitely deserves to be watched.
