He's doing a great job on the Flash, probably my favourite character. Hopefully he stays for the long run. We all know how capable he is so hopefully the writers make the most of it.
I thought the same thing during his first episodes in Flash. But since maybe episode 7 he suddenly started to look pretty good, and at least 5 years younger, than in the previous episodes.
I found out he broke up with his girlfriend around that time and started drinking and was rumored to have used drugs. Reportedly he's doing much better now which could explain what you said. I'm so glad he's back to his old self.
