I loved Brandon on Chuck. He played the straight guy. He gave a very nuanced, subtle and deadpanish performance. But there was always a dark edge to his character. And the music emphasized it.

I liked the shifts in his character throughout the season. First he was this cold, very professional and controversial spy in the the first episodes obsessed with destroying the Ring for the death of his wife mainly, lol. Then he fell a little bit for Sarah and tried to start a new life with her until he learned that the woman he was involved with was the killer of his wife. And worse, the order was given by the same institution he was working for: the CIA.
He then turned. He was still conflicted on it, which was clearly shown in the Other Guy episode (superb ep, btw). Then Chuck killed him, but he was revived by the Ring. And he returned completely evil and on revenge mode. He had nothing to lose anymore and he didn't care. He just wanted to punish all of those who stood in his way. Like the showrunners said, he was the Two Face of the Chuck universe. He was always going to become Chuck's arch nemesis. The writing wasn't always great, but it worked overall for me. He is simply the best and more realistic villain that show's ever had, imo.

Brandon also got good reviews for his short role in Zach and Miri, and got really great reviews for his role in Scott Pilgrim. He played evil, badass and hilarious at the same time. He was awesome.
