What I have long wanted with going back to TV-14 was just edgier storylines. Even though I know the WWE really made profits with the PG era and becoming a "family" product and making their shows about the entertainment and really aimed toward kids, to me it never made sense that a show that runs from 8pm-11pm on a school night would make kids their prime audience. I remember growing up I had to sneak the television on to watch RAW and that was when it aired from 9pm-11pm.
I just didn't find it all that interesting of a product when John Cena or Roman Reigns were giving a promo and their major dig at their opponent was, "You go doo-doo in your pants."
Make it TV-14, parents who let their kids watch RAW from 8-11 on a Monday night are still going to let them watch RAW whether it's PG or TV-14, it's pro-wrestling for Godsake.
