Well, This can be tricky:
Most people look down on wrestling with the stigma that it's fake. They dont understand that it is not the actual "wrestling" that we cheer for, but rather the entertainment of the storeylines and the story of the "storylines", that we cheer for durring the match. Proof in point; whenever a wrestler lands a prime-time interview with the main-stream-media, the first question that is allways asked is "do the fans know it's fake?". And the wrestler has to explain that it's just a form of entertainment with storylines, much like a soap opera, that the fans are cheering for. The ability to suspend dis-beliefe falls in-line with the story-telling of the product.
Chances are, if you didn't become a fan by your early teens, you probably never will.
Another problem is the "PG" era of today that is driving out the 18-24 demo. If the product has a lot of elements geared torwards children, It will turn off any potential new 18-24 demo viewers.
Let her watch a lot of Orton and Cody.
