Some dude posted this in the comments section of the toho-scope's link,

If Moffat had kept any sense about him last season, instead of blowing up the River Song story line to absurd proportions and making it unpalatable for future consumption, he could have gone with a 'young' River Song as the next companion. Imagine if season 6 hadn't featured River AT ALL, imagine if she wasn't the Pond's unlikely child and imagine if she'd retained her mystery. Imagine, then, her 'first' meeting with the Doctor as a very young woman, a student, with no knowledge of him whatsoever - and watch them have a battle of wits in the Tardis. THAT would have been a story line worth waiting for.

And I very much agree with it (except the battle of wits bit, that is stupid) . I have always really disliked River. She is obnoxious, and by far the worse thing about Smith-Who. The above idea would have fit continuity wise (prior to last season), and really provided the opportunity to make River a likeable character and to make sense of the relationship between her and the Doctor, as it is, it feels like he married her and is fond of her simply because she keeps telling him how much he loves her and how important she is to him. It has never really worked, Amy and Rory were such great companions, they made the whole rid past this train-wreck of a story arch bearable, but how much better would it have been without so much time wasted on the River Song BS.
