I don't think it's being pessimistic considering the last two Wrestlemanias were way too long, and this year's show looks to be even bigger. If you have to break your show into sessions to keep the crowd from passing out, your show is too goddamned long. No one's "forced" to watch it all of course,
It used to be a bucket list goal of mine to attend a Mania at some point, but I couldn't possibly imagine paying even StubHub prices to attend a 7+ hour stadium show.
