Hassled I am indeed from the US, but live in the UK now, and I have to say that I think the American accents are absolutely flawless!
Actually, I am embarrassed to admit that I didn't even know that Damien Lewis wasn't American until about half way through season one, and only knew about Quinn and Estes because of this thread. 
Just amazing. Even since I have known, I have yet to hear a slip up from any of them.
I saw Damien Lewis on Jonathan Ross, and it was absolutely bizarre to hear his English Accent.
I can't help but think that the Nazir plot can't be over, there has to be more coming that he had planned, maybe Brody is in on it still? Nazir said that he knew that wouldn't leave the US alive, so maybe all part of the plan? I have no idea!! Can't wait though.
Am I the only one not looking to watch it early? I kind of like the suspense and mild torture in the waiting :)
Also, if anyone could recommend a series that I could watch on DVD or something between now and next year, that would be great. This is the first show I have ever been truly hooked on. I used to travel too much for work, but now have kids and don't go anywhere!
Just trying to plan ahead for my homeland withdrawals.
