I really enjoyed it. I can see why he was excited to get the script. He did such an amazing job at showing exactly when the Doctor goes overboard, breaking all of his rules. I kept wanting someone there to stop him. Hoping a new companion would appear and balance him out like they've always done in the past. Arrogant Doctor is sertainly not as appealing as sorrowful Doctor, but it gives the character an almost human quality. No one is perfect, like the tagline from Jekyll and Hyde ages ago, there is such a fine line between a good man and a bad. It gave an interesting debate. The Doctor isn't some perfect all-mighty being, and it gives him a chance to see where his opponents are coming from. Though what he did was justified, he knew it was wrong as he was doing it. Which I think David played brilliantly. So looking back on the episode, I enjoyed it a great deal. But while watching it, it just made me feel, I dunno- not exactly "scared" of or for the Doctor, but more uneasy of him. Which I'm sure was intended! :)
Aah, this tv show is so captivating!
