The problem with the Journey's End is that the resolutions of everything came just a bit convenient: Sarah Jane Smith was saved by Mickey and Jackie who happened to teleport just by her car? Okay, fine, I accepted it. The Doctor just pointed the regeneration energy to the severed hand after he healed himself so that he won't be fully transform, fine, that's okay too. But to have Gwen and Ianto saved by Toshiko's completed Time Lock mechanism is just too convenient, not to mention contradicting. I mean, what is it activating now? You don't see it activating in the finale of Torchwood when Toshiko herself was attacked by Gray? And since it was a fatal attack that killed her, when did she actually have the mechanism completed? Then there's the whole cloned Doctor that is half human. The writer can't find a way out of the romance storyline of Rose and the Doctor, so they conveniently created a clone that is half human that can stay with Rose in the parallel world? That's kind of like since the real Buffy isn't ready to be with Angel, so let's have a Buffybot for Angel!
Despite all these complaints, I still do like the episode. The epic scale is truly epic, not only the massive cast, but I mean, it's not just the whole universe was in danger, but every single parallel universe and everything in reality as well! That really is everything!
Donna's fate in the end is tragic. I don't mean herself because she won't know about it for the rest of her life, but for the people that are in the knows, especially the Doctor. To erase her memories and make her go back to what she was, a selfish, clueless, rude person, instead of what she has become after traveling with the Doctor, it's a punishment that is worst than killing her.
The ending was desperately sad for the Doctor, he's truly alone, more than ever. More than at the end of series 2. Back then even though he and Rose were separated by the parallel worlds, he know he's thinking of her and she is thinking of him everyday. And if one day he was able to overcome the obstacle, he and Rose can be together again. Not this time though, because Rose don't need him anymore. She got the Doctor-clone. Someone that is the same as the Doctor, with the same memories, same personality and physiques. How heartbreaking it must be for the real Doctor to see the person you love kissing a clone of yourself, someone that is exactly you but not really you. Knowing that you have no reason to come back because the person you love don't need you anymore. Then there's Donna, the one friend he has that truly understand him, someone that can snap the Doctor out of it with her attitude, someone that he can truly have fun with without worrying any romance complication. Donna's unique because unlike Rose, Martha, Captain Jack, and Sarah Jane, she is the only one that the Doctor is close with that wasn't in love with him or had a crush on him, ever. And yet she's brutally taken away from him forever. With the rest of the gang all found their own lives to live and their own calling. The Doctor is all alone.
Points of interest/excitement:
1) I always wonder why on earth would the controls of TARDIS so difficult that you need the Doctor dancing around in circle to control it~ most of the time he don't even have enough hands to handle it~ Now we know! Cos there's suppose to need 6 people to control it at the same time!
2) Everyone in the TARDIS! That was the best moment!
3) K-9 made an appearance finally!! Awesome robot dog!!!
4) Finally the mystery is solved – Gwen Cooper and Gwyneth in the 18th century is truly related!
5) They didn't forget about Pete Tyler, he was mentioned!
6) German speaking Dalek!!!!!
7) Captain Jack's suggestive remarks: When running into Mickey and then giving him a hug "Good to see ya!...and that's a beefcake…." "Mickey replied uncomfortably, "and that's enough hugging"; When Captain Jack heard about there are 3 of the same Doctor: "I can't tell you what I am thinking RIGHT NOW!" LOL, aside from saving the world, he only has one thing in his mind~ haha~
8) Martha's touching reaction to see Rose on the screen: "Oh, my god…he found you."
9) The Doctor told Donna's mother that it wouldn't kill her to let Donna know once in a while that she love her.
10) Martha and Mickey walked away with Captain Jack…hmm….Torchwood lost Toshiko (technical support) and Owen (Medical support) in their own finale earlier this year….I see replacements!!
11) Rose storyline comes to an end, with Donna lost her memories and can never regain them otherwise her brain would burn out, and Martha leaving with Jack, Sarah Jane goes back to her "son", will the Doctor travel with someone new? Or old? If it's someone new then I can't really speculate, but if it's someone old – what about Sally Sparrow from the excellent Blink episode? Or the Doctor's own daughter Jenny? Or will we finally see the future adventures of Professor River Song?
