Grey’s Anatomy

So, what exactly is the big deal with Grey’s Anatomy? I keep hearing raves about it, but I’ve been giving it a shot tonight, and the writing is… well, not awful, but uninspired at best. I’ve also heard it described as a guilty pleasure, but I don’t see where the pleasure enters into it. Even though House has degraded a bit this season, the writing is still 20 times better. Anyone want to tell me what the heck the draw is here?
