Honestly, I felt that Summerslam was overall pretty good aside from the pre-show and the 4 screwey finishes.
Seriously, the Bludgeon Brothers/New day fight ended in DQ. AJ/Samoa Joe ended in DQ. Miz/Bryan had Miz cheating, and Lesnar/Reigns was hugely influenced by braun.
Of them, I do think that Joe/Styles made sense (though this was not the place for that sort of end) and same with Miz/Bryan (Summerslam is not the place for screwball endings), but the only ending I liked was Reigns/LEsnar. I genuinely thought we were getting a triple threat match.
