Advisiories are give when they are on a "Network" channel within the still alotted timeslots that minors will be viewing (or those with quesey tummies). Cable channels are getting into this too but they aren't big on it as "Network" Channels are.
I didn't mind the story, it didn't hold my interest all that much and the killer didn't hold my interest at all, what did hold my interest is the fact that they really as allmaple said tried to make the victim more center stage, right down to the killer not even feeling a thing about it as he said in the ending scene on his confession.
The killer made that most notable to me when he said "they had "Empty Eyes"" bring to front the name of the ep, and the fact that the victims & the crime were to be the main reason for the ep, and everything else surrounding it second string which only gave more notice to the main.
As to Greg, I admit what the city did by settling does make it seem like they believe, or that he looks guilty, BUT here is the catch in all this, Greg was represented so why wasn't he informed by his representive instead of by Grissom. It seems to me IMO that maybe there is a chance that while the city might settle that does not necessairly mean that Greg's representive or he himself would agree to that. Unless his representive was produced to him via the city in which case thats a conflict of interest and Greg may have a case for that and still be able to stand on his own. The civil suit was against I believe "The City", "The PD and/or Lab", & "Greg", now from what I gather the first two sets have decided to settle, but for it to all be over so would in effect greg.
As to Hodges, I don't necessairly think he was in the wrong by answering the phone, many states a lab tech wouldn't be in trouble for answering and even giving the news. Considering they knew who the girls were so the Family should have been given the info as it was Warrick had to tell the one girls grandmother. I would think if anything as I have said before if hodges were to get anything at all it would be told next time, let it ring, then pass off the info to either one of the CSI's (ie Grissom/Catherine, ect) or to Brass/sofia, etc.
I have noticed alot of people mention Warrick going back to his old haunting ground to give the grandmother to the girl the bad news and hear of his youth and family. But unless I missed it I didn't see where it was mentioned that he said his grandmother passed away, which means unless the writers come up with another family member, we won't being seeing any from him. As folks have mentioned liking to see family for him.
Though I haven't given my full review of the ep my Overall number on this would be 8.5/10 The fact that they went slow with the beginning and moved quick with the ending it didn't IMO even out at all and just kind of took from the story and its focal points.
