Overview: Season Five

Before re-watching each episode individually, I decided to jot down a few notes on each one based on my memory alone. Max pitched in a few times, but for the most part these thoughts/notes are mine and based on nothing but my memory and knowledge of specific episodes of Doctor Who.
I'll start with Season five, then post six tomorrow, and seven on Tuesday.
General notes:

• HUMANITY is a major theme. As the Doctor gets more God-like, he draws a thicker line between himself and the human race. Episodes that feature this theme are starred. *
• Any two-part episodes are considered as one unit. Their story line is split up, but their themes continue to develop and character arcs stretch from the beginning of one to the end of another
• We consider CHARACTERS over "Real-world" circumstances (for instance, rather than considering the fact that Tennant stepped in because Eccleston had to leave, we would look at Nine's departure in the storyline, and Ten's arrival.)
• Memory/forgetting is another important theme, in both Doctor Who and Peter Pan
