Money in the Bank was literally the only PPV I could think of as standing out at all.
I mean I hardly watch any PPVs at all but that was the only one I actually bothered to watch any of (Wrestlemania included) so that's worth best PPV of the year mention from me, specially given the huge main event match was actually quite good.
