You know, having first watched this part of this series long after it had already aired, I had never seen Born Again until just now.

It's, uh, fine. Not anything too special. Rose's reaction to the regeneration felt quite well done and Piper acted it well. Tennant still seems to be getting used to things, though. It is really neat seeing him so early in his career after the 2014 specials, but there is something a little off about the whole special and performance compared to when the show hits its stride with the Tenth Doctor.
