I haven't watched the entire thing. From what I saw, it did make me want to change the channel. That I did.
I wound up watching
another episode of CSI NY from season 4.
Serial killers are hard, you want them to be deranged enough, at least from what we see, and altered enough to believe their actions are the right ones.
Vegas tried to pull it off, with better results from what I hear, this season. Yea, some of it fell flat, other parts didn't.
I think the same goes for Shane Casey. Edward Furlong is a terrific young actor, he can pull of stuff like this, but the whole premise around Shane's behavior became baffling and from what I read, also fell flat.
I tend to like my villains with a little more depth and sometimes you don't know exactly what side they are on. This whole Danny/Shane thing had that promise of Danny trying to reach out to him, bond with him over the prior sins of their respective brothers, etc.. but again to have Shane go completely batty (for lack of a better word) about Danny's inclusion about Shane's brother's death just didn't do it for me. Or didn't do it enough to make me watch this dramatic conclusion to the storyline.
So, I'm assuming your review is excellent as always, and might I add you did a good job getting all the reviews up in a timely manner. You are a hard working lady.
I will save my thought until I do actually get around to watching this final episode of season 6.
