I had never watched Trauma, but on Maria's recommendation looked it up on Hulu and have watched the first 4 shows so far. I agree, it is/was a great show! But it seems as if the really good ones are always the ones that get cancelled too soon. Or else my taste in shows is radically different from the general public's.
Trauma WAS very intense, though. I have to watch an episode of Antiques Roadshow afterwards or I'd never be able to fall asleep!
