I keep asking myself if I'm ready for the David Tennant finale, and I'm not quite sure that I am. It's gonna be hard and emotional and if this episode is any indication, Tennant and Russell T. Davies are going out with a bang, and rightfully so. Of all of the episodes Davies has penned for the series, "The Waters of Mars" ranks somewhere at the very top. It's a little more menacing than what we've seen before and Davies takes our favorite Time Lord down a darkened path that will disturb the faithful, while recalling echoes of the classic series (remember the Valeyard?). But Davies really shows his brilliance and passion for the Doctor with this episode, and even as the Doctor is reacting to the situation in frightening ways we'd never dream of, there is the underlying reason for his behavior, which Davies reminds the audience of, which in turn makes your heart ache for the Doctor and his truly tragic existence. This is an episode full of pathos, and Tennant absolutely dazzles, proving exactly why he will be missed by millions the world over. Lindsay Duncan as Adelaide Brooke is also a stunner in her role and her final scenes with Tennant, as she confronts the Doctor and tries to set him straight, will send a shiver down your spine.
All in all, it's going to be interesting to see how they bring the Tennant era to a close, to the heartbreak of a multitude of fans, and I hope it lives up to the expectations. But even if it does or it doesn't, it ain't gonna be easy. David Tennant has completely endeared himself to the Whoniverse and it's going to be hard to watch him leave and watch that first episode without him. But that is the nature of the Doctor Who beast, I suppose. Change is never easy, but the next chapter in the life of our favorite Gallifreyan awaits. As for Russell T. Davies? The Whoniverse owes him a debt of gratitude for resurrecting our beloved time traveler and returning him to our screens and hearts with such brilliance and care. Bravo to all!
