So basically having Johnny Depp instead of Matt Smith would be like getting this totally awesome toy (Smith). This toy is awesome. It's pretty much everything you like and you're having boatloads of fun with it. And so, you wish to just carry on playing.
But then someone decides, HEY, YOU NEED THIS TOY (Depp). Yes, technically it's shinier and has more buttons and kung-fu grip and whatever. But you don't really want it or need it. Still, everyone else is telling you to play with this damn toy, that doesn't even fit what you want it to do. You want your old toy back.
I'm not sure where I'm going with this other than no thank you, Johnny. Or RTD. Davies, you can go fuck with Torchwood as I'm considering that whole mess past S2 a wash. Moffat is doing lovely things with DW. I like that a series ended and I'm not wanting to commit suicide. I like feeling hopeful, that I'm going on adventures with the Doctor. Not that he's some sort of tortured vehicle for whatever angst you want to shove down our throats.
