I love MI-5, I really do, but the actress playing Sarah has the worst Boston accent I've EVER heard in my life, plus she drops in and out of it constantly. Seriously, just because she's from Boston, doesn't mean she even has to have an accent. I live in TX, and many people even here have no accent at all. She's an Irish actress, who clearly sucks at dialects, so why have her do a caricature of an accent? It's soooo bad! It makes her sound unbelievably stupid, and she's supposed to be some brilliant CIA agent. I feel so sorry for Richard Armitage having to listen to that grating, vile obnoxious voice for months of shooting. I literally am on this sight because I was looking up how many more episodes did I have put up with before she hopefully dies a horrible death. She owes Bostonians and Americans in general a huge apology for what she's done to one of our regional dialects. Please kill her off already!
