One of those episodes that I have to see again and again for the pure pleasure it is, it's wonderful at so many levels that makes me think that when The Good Wife is good, it's my favorite show. Many stories go at the same time: there is a wonderful dialog about racial bias with the Peter subplot, but the heart of the episode is at Elsbeth Tascioni, one of the better recurring characters of the show, which makes the whole firm move to defend her case as she is that brilliant lawyer.
Maybe you could criticize "Je ne sais what" for being too safe for the characters: they almost have no danger and they do not face any of the usual contradictions; in fact, the only character that actually suffers is Will, gloriously out of his field in a sport tribunal. The rest is the usual "two simultaneous trials" format that this show has taken in the last weeks, but the difference is in the craft: screwball rhythm, memorable punchlines, and great characters as the European tribunal that speak in french. Also great editing, lighting and composition, and the usual great dressing, but above it all, the sense that all the characters are alive, doing what they do best, and taking care of each other. The last minutes of the show were wonderful, with Tascioni running and being brilliantly manipulative with the tribunal. She's so charismatic, so funny, so lovable that she deserves a spin off. 10/10
