I've had two stopping points. First was in 2011, right between the New Nexus and the CM Punk mega run. I was just bored, the matches sucked, the stories sucked, everything sucked and I wasn't having it, so I left. I didn't pick it back up till 2015 with the return of Batista. I watched pretty religiously up until the Reigns Strowman HitC match where Lesnar interfered. With that I soft dropped it because of just how freaking stupid it was, it showed me WWE had no respect for me so much so that the megaboss ppv main event led to nothing. Soft drop means I stopped watching but still watched reviews and such. That was until HiaC Fiend vs Rollins one year later which was somehow worse, so I quit altogether. The last show I watched was the Rumble and it didn't entertain me enough to even soft pick it back up
I should specify HiaC is my favorite ppv, so having horrible finishes there really hurts, especially two years in a row.
