River Song is starting to grow on me at first I was so put off by her but as the series continued I thought she may not be that bad.

I have my own theory on River I think she is the Omega that was in the Old Who ( I not sure if I like calling it that) but anyway. When you look at her in the episodes she is in she is always has the greek symbol "omega" on her person or around her. (Just a rambling thought)
