#4 The order of the matches

I am sure I was not the only one who was disappointed and angry when the WWE Championship match was announced as the 5th match in the 10 match long pay per view. However, as the show carried on and the remaining matches took place, I realized WWE had presented the SummerSlam card in a brilliant way, something that had not been done in WWE till that point.
It was not one complete card, but it was an amalgamation of two separate wrestling cards, each main evented by a World Title match and separated by an in-ring segment. Both cards had a hot opener (Intercontinental Title and Bryan vs Miz), a women's title match, a secondary title match and a squash match.
Not only did it give the crowd enough time to gather up after a big match, it kept the crowd invested throughout the pay per view. Intentional or not, I don't know, but it certainly worked pretty well for the WWE as none of the matches were booed by the fans, not even the Universal Title match - and that in itself is a very big deal.
