Grey's Anatomy Finale

I love this show but the finale just piss me off. I know some people probably have not seen it yet but you know what Meredith gets on my nerve and so does Christina. Izzy is an idiot and so is Alex. George needs to get a clue of what he wants. He is always one character that annoys me. He gets the girl and he is not sure if he loves his wife or Izzy. Stupid characters!
