Season 5 Episode 1 gave a good preview of what to expect for the rest of the season. And it does look exciting. Matt seems like a good fit for the role. His British accent is a bit stronger and harder to understand. But I guess that is part of The Doctor's charm.
Amy Pond, The Doctor's new companion played by Scottish actress Karen Gillan, is certainly a refreshing look compared to the previous season's Donna Noble. Some Dr. Who fans think she's the best looking companion so far. I'm not much a fan of redheads, I guess. I still vote for Season 3's Frema Agyeman as the best looking companion to date. :) But that doesn't take anything away from Karen who also dabbled in modeling and minor TV and movie roles.
Here's looking forward to watching the next 12 episodes.
