Women when your really attracted to men. If he is only rating the TS as a high score I think he just is not attracted to women and may just have a wired angle.

This is probably a guy who complains about everything. The reason he liked the TS is she put something in his mouth to stop his bitching!  

He could just be an asshole that's always a possibility *shrugs* lol. Some guys are just harsh scorers and/or are hard to please so it's virtually impossibly for them to actually have a good time.  
If he/they have a constant string of experiences rated that bad well it just might be him.
