Jenna Louise Coleman is hot but she still can't save a show that has terrible poorly though out concepts such as;
1. Having your soul uploaded to the internet is poor sci-fi but made worse by the fact that there was no direct interface between the human subject, nothing to actually facilitate the upload. Are we really supposed to believe that being surrounded by this wi-fi that you can simply be uploaded.
No more crazy than the neural relays from Silence in the Library/Forest of the Damned. In fact, I was waiting for 11 to say something like "You can't have this technology yet...you shouldn't have neural relays until the 23rd century at least. Where did you get this from?" But I did not...even so, it's not like it's a technology we haven't seen before.
...that and the spoonhead robots do the uploading with a beam, not wifi.
2. In lastnight's episode the Doctor and Clara flew through space without any kind of life support gear, no helmet/oxygen tank. Even Tennant donned a space suit when he had to face that Satan thing.
There was also an entire civilization of people living on the rings and they rented out those mopeds for venturing out INTO the rings, so it would seem there was some sort of atmosphere, natural or generated.
Personally, I'm loving the new series. (Well, the JLC episodes, since we're still technically in series 7) I just hope they don't make her "too important."
Rose for me was a great companion for me because she was just a normal girl amazed by everything she saw -- she was basically us on the TARDIS -- and it wasn't until the end of her tenure that she became more confident and powerful. Amy had no such arc. She started out fierce and tenacious and just stagnated there. There was no room for growth.
I like that Clara found a way to help the Doctor last night, but I just hope that she doesn't ALWAYS have to rush to his defense and that she gets a chance to just be awestruck for a bit...as we all would be.
