As I said in the thread about the revival, I don't know how I feel. While the original should have outlasted SVU and should not have been axed for the failure that was Law & Order: Los Angeles, it has been over a decade since this last aired.
And many of the existing cast members are now on other shows. And, frankly, the current writing on Dick Wolf shows does not exactly inspire confidence in me that the revival will not end up schitting on the original. And some, let's be honest, are too old now. (I adore Sam Waterston, but the man is over 80 now.) That means new blood, and casting is very hit or miss.
Sometimes, things are best left alone. (But I will watch the first episode to gauge an opinion should it truly come to pass.)
