Unlike the other reviewer, we enjoyed the trilogy. We don't normally watch NCIS LA, but had no problem doing so to complete the story. Whining about it is not necessary.
The one thing that bugged us was that the company name was (and pardon me for forgetting the actual name but I think it was Haven so I'm going to go with that here) Haven LTD, or Haven Limited. But instead of saying "limited" the actors would say "L T D". This happened a bunch of times. It's like the writers don't know the meaning of the abbreviation. Either that or it was some running gag behind the scenes. Whatever, it was annoying.
