I think the problem with the last group of episodes and what I think they messed up later on in the years is the flip of unsub first and investigation last. Early, they used to tell stories where we didn't know the unsub and we would find out with the team but these days it's a formula: Crime committed, known unsub, team gets case and try to figure out what we already know. It's getting boring.

Edit: And making basic procedure mistakes that even us noobies wouldn't do without a little research. I am sorry but there is no way in hell you going to get me to like Garcia's episode, that was all kinds of procedural wrong.
