My husband and I watch 4 shows obsessively: CSI:LV, L&O:SVU, House, and Grey's Anatomy. We have DVR, so every single episode of all the shows are taped (needless to say, we have to stay on top of watching the episodes and deleting them or the queue gets filled rather quickly).
House is one that I will probably cry if I miss. I didn't get to see the first season (so thank God for USA, which plays the repeats) but I love the second!
I've liked Hugh Laurie since... probably Sense & Sensibility. He's hilarious. I think the reason that he speaks with an American accent is because the character was written to be American. Plus, his bedside manner is non-existent and that's really (supposed to be) abnormal in American medicine. British people are known (over here, anyway) for their detatched demeanor.
