I know that I've been looking at Reid differently since his S4 two-parter. MGG plays pissed-off Reid very well indeed, and he was seething in that second ep as soon as he found out his dad had always lived ten miles away from him and his mom.
When he had the victim's dad in interrogation and the cop walked in, he spun around, pointed at the cop, and told him to get out because he was taking over the investigation--had me fanning myself. Confrontational Reid is very hot!
I haven't seen the whole ep with Frakes yet (I'm hoping that CBS will rerun it this summer), but I did see that scene on Youtube. When Frakes rather smirkingly called him "Doctor," Reid turned that back on him in equally cutting tones and sliced him to bits. Love watching that.
Reid is my favorite CM character, and has been since midway through S1, in the beginning because he was the quirkiest of the bunch, but later because I just love how MGG has played him. Yes, quirky as hell, but he conveys emotions of all types wonderfully.
Garcia is my second favorite, and I'd love it if she got more screen time but understand that they really can't give her more and keep her character believable as an office-based tech. Her relationship with Morgan is one of my favorites on tv right now.
Hotch has grown on me big-time. In the beginning, I thought he was just an officious grump with a massive stick up his behind, but starting with LDSK, and then the S2 opener when he and Gideon are holding vigil in the hospital while Elle is in surgery, and then in Revelation when he has the team list his faults, I started falling for him. Omnivore was on last night, and that moment in the alley when he's weeping over the Reaper's massacre in the bus--oh, my! I was verklempt.
