I regularly watch Law & Order: SVU. This season, they seem to be doing a lot of stunt casting. The most recent episode featured Robin Williams in a dark but funny role, which is something he does well. This is one of the weaker episodes I've seen - and not because the performances of the actors. The writing was lacking on this one.
Robin Williams's character toward the end of the episode somehow managed to kidnap Olivia, one of the detectives. Although her entire squad knew of her kidnapping, only her partner Eliot showed up at the scene of the crime - alone. Not likely. It's more likely that all of her co-workers, including her captain would have shown up to rescue her.
There were other problems with the episode - again none of them performance related. But the above was the weakest part.
