I don't think it's going to happen.
Seems like it was a one-season thing. I purchased it on release day because I'm a huge Law and Order
(mostly SVU) fan. Maybe there wasn't enough buzz around it?
I think The Walking Dead is the current darling for TTG -- and it should be, honestly.
Still got my fingers crossed; would love another season with some of the other detectives from the three series. Hopefully something with Stabler from SVU!
