I've watched all the episodes, and I am really getting into this show.
Obviously it isn't completely realistic. If you want a realistic medical show, go watch a documentary. That's what documentaries are for... TV dramas are for entertainment.
And entertain, it does. The first episode seems a little shaky, but afterward the characters develop really well. They're all likable and engaging. In every episode, amidst cool rescue action, interesting aspects of their jobs and lives are examined. Eg they explore the characters' feelings and actions when dealing with issues like homosexuality, accidentally killing patients, friendship/hierarchy conflicts, being exposed to terrifying contagions, and all sorts of other things. Something completely different happens in every episode. It's interesting, fast-paced and unpredictable. It's also slowly getting better; they certainly don't seem to be running out of ideas.
Basically, good show in every possible way. Except realism, but that obviously isn't the point.
