If I must say so... ALL five of the student actors need to do work. Their acting is so "soap opera" based & two-dimensional with honest moments here & there. Viola Davis, her husband, & the female paralegal (I assume) shine.
I will say the guest actress who played the 1994 terrorist bomber was the best guest actress so far. She brought realism & authenticity to the show that Viola couldn't carry all by herself. The car scene after they left the jail was very interesting and great to watch thanks to her.
