I'm not the best person right now to navigate the balance between effective drama and realism in medical shows. I favor the boring stuff and accuracy over the fanciful - and mostly because we get so much of the latter in a majority of med dramas so I crave a difference.
Either way, it's going to be difficult to harness the laymen/women with something that's not too depressing. I'm really hoping that people will take to this the way they took to BSG. It's dark but it's real and more importantly, it's television that makes you think seriously about mortality.
