Personally, I want to see more with Morgan. We have his backstory episode and I guess the season finale for season five, but I kind of want to see more with him. 'Big Sea' was an interesting episode and he does have a few moments, but another episodes dedicated to something of his past would be nice. Also, even if Hotch's character is pretty complete, it's not like there's been complaints about it or anything. Hotch is in no danger of being less liked by the fans yet.
Yeah. Well, he was good while he lasted. Served a few good things for the cast.
