To my knowledge, football fans don't complain because there weren't enough exciting "hail mary" style passes thrown, or enough flashy slam dunks or buzzer-beating half court shots in basketball, or grand slam home runs in extra innings in baseball. The fans of those sports watch for entertainment, sure, but their entertainment comes from enjoying the athletic competition of the sport. All the other stuff is just icing on the cake. Why can't boxing fans be like that?
