Is "Revenge" Losing It's Point?

I keeping looking forward to Sunday night but then I realize that Revenge is on hiatus. I don't understand why the producers decided to take this rather long winter break. They already have sufficient viewers on the edge of their seats anticipating the upcoming episode each and every week. So why would the network make the viewers hold on until March for another episode?  You would think people would quickly get sick and tired of this all waiting around (zzzz)  and move on to another show. Anyway, after watching the last episode before the break, I feel like this show has unquestionably taken a turn for the worse. (spoilers ahead) I mean they left us implying that Emily had a blackout and slept with Conrad. Seriously? We know she had a head injury but why does Emily continue to have all these blackouts? I just don't like the way in which they turned Emily into this fragile girl. She was badass when the show first started. Her list and the pictures she was making progress by crossing off people that she was targeting for her vengeance. I thought the whole intention of the her being in the Hamptons is for her to always be one step ahead of the Greysons. It is much more rewarding to the viewers for us to see Emily actually carry out her vendetta. Unfortunately the writers have completely turned her in the opposite direction. Now she's just a victim that has accomplished nothing in her quest for revenge.  One might think that after planning this lengthy plot, she would have achieved something but she has accomplished  practically nothing. I hope that when the show returns in March, we get the old Emily back and things start to turn to her favor.
