Benson squeezed all her over-the-top histrionics into those few mins she had in the Hospital with Tiana. The way she crouched with her face inches from that poor girl's face reminded me of Detective Goren in CI, how he would pull those mind games, hovering over the defendants when he interrogated them. But that came naturally to Vincent D'Onofrio who portrayed the eccentric, highly intelligent, out of the box detective very well.
Stone seemed to have taken some acting (?) lessons from MH in his courtroom scene, with the tremulous voice, glistening eyes etc. Sheesh, next these guys will break into an Aria. Long for the understated, realistic and gritty performances by Sam Waterston, Jerry Orbach, Epatha Merkerson, etc.
