I don't know what a Colin Baler is. I assume it's English; put another way: skin like raw dough, affected effeminate mannerisms, won't eat anything that hasn't had every atom of flavor boiled out of it, and gives off strong implications of an unhealthy attraction to its first cousin.
Like an Appalachian hillbilly with a posh accent, to put it another way.
I certainly found a lot of stuff RTD did obnoxious (the endless "ooh I'm going to die soon" thing with Tennant comes to mind! And Rose having a Doctor Sex Clone) but compared to Chibbers this is going to be a massive step-up. RTD actually knows how to, like, write a story, which it turns out is pretty important! And he's already successfully relaunched Doctor Who once.
