Oh, I hear him trying that accent. I guess it's easier to tell he's not American if you are American. Just like I never really buy into American actors playing English roles or vice versa. Yes, I have heard Henry Cavill speak with an American accent in that Hellraiser movie and it didn't work for me, I still can't wrap my head around him being cast as Superman. No, don't bring up Bale, he also does that "talks kinda slow from the back of my throat and still somehow sound nasally and whispery" thing that still does not sound American.
But onto Torchwood. So far it's ok. Seems like your regular season of Torchwood to me, just with an extra setting thrown in. But if they can operate on other planets in previous episodes then why not the US? I just hate that the show has become so separate and apart from Dr Who.
