I read other reviews slamming the show and everyone has a right to their opinion. My thought is, if you don't like it, don't watch it. I personally enjoy it, along with the Chicago franchise (Fire&PD). The crossover events are especially fun to watch. Is the use of accurate information on medication always correct? I can't say as I am not a doctor.
I watch it because I like the characters and the stories. I'm sure there could be improvements, as with most tv. But this is not a documentary, its meant for entertainment. At least the characters have back stories. Lives outside the hospital. Dick Wolf has smartly created a network of series that all intermingle and its interesting to see how the New York shows come into play with the Chicago shows. So, just try it.
And I don't mean to offend but to say it's like a soap opera is kinda funny to me because what is Grey's if not a soap? Most medical dramas have an element of such as well as miraculous cures at the end of the hour.
