Why do I feel like Robert Pattinson is the 11th Doctor?

So...new Doctor. He's a looker, that's for sure. The thing is, I'm worried they're going to get even deeper into the "sexual tension and genuine relationship possibilities with the companion issue" than they did with 10...and after the whole Rose situation, that's clearly not a good thing. Maybe it's time for more than one companion at a time. Then there could be sexual tension between the two of them, like Sarah Jane and Harry (but not like Rose and Mickey). 

Well, I'll try to enjoy the Tennant days that are left and worry about making a judgment about this new kid when he starts next year.
