Americans can't act?

I have been watching a lot of the new shows, and I noticed that many of these American characters are being played by foreigners. Take the Bionic Woman for example. She is an all American girl, yet Michelle Ryan who plays her says things like "bugger" and "wanker" when she is off the set.

Alex O'Loughlin makes an adorable American vampire on Moonlight, but does his lunch include a Vegemite sandwich and a quick listen to Men at Work? He is quite the Aussie.

So what's going on? Is our American accent too weird? Will people who watch a lot of TV (like me) get used to the way these fake Americans speak? Why not just cast Americans as Americans? OR can we cast foreigners as Americans and the let the Americans fill the foreign roles? Then it WOULD be acting!

Anyway, here is a list I compiled. I kept it to the network stations and the CW. I am sure I missed some, so please share if you caught some I didn't. And God bless the Aussies for continually cranking out one hottie after another and sending them to the States.
