Liked the show from the start - great cast, wonderful ideas of social medicine for the US, brilliant doctors caring only about patients, nice story lines, and many emotional moments. But with every episode the plot became more improbable with authors throwing all possible troubles at poor characters. At the start of Season 2, when the ambulance got into an accident on top of other misfortunes happened earlier (not disclosing details here), it became too much and I stopped watching. You have to respect your audience. Too bad - the show could be one of my favorite!
