Republibot 2.0 has already reviewed this episode (Read it here: http://www.republibot.com/content/reviews-doctor-who-waters-mars ), and I have little to add to that, so I’m not going to bother with a synopsis or a formal review. I did just now manage to watch it on Youtube (Link below the jump), however, and as we’ve got no other real content today, I thought I’d offer my own observations.
