It was a nice middle ground between Scrubs (a favorite of mine) and ER (stopped watching about 10 years ago). A lot less silly than Scrubs, but not as serious as ER. I happened to be watching with my mother-in-law, and she didn't seem to like it as well. She kept commenting how things couldn't really be like that in a hospital. I think for her, ER = plausably real, Scrubs = pure fantasy, but she couldn't really put Grey's Anatomy to one side or the other -- it moved around a bit. Anyway, I'll watch next week but I'm sure she isn't alone in feeling a bit disturbed by it (comments like "they wouldn't let someone operate by themselves on the first day," and "they wouldn't really be that mean to them").
