#1 Avoid too many non-match segments

Over the last few WrestleManias, there have been a few non-match segments. The New Day, as hosts of WrestleMania 33, had a couple of effective cameos, while there was a mid-show concert with the likes of Pitbull and Flo Rida at Citrus Bowl that night. Last year, we got talking segments which preceded matches, with Elias's appearance being the biggest example of it. This year, we already have a couple lined up, but it needs to be limited.
Alexa Bliss is the host of WrestleMania 35 and will almost certainly open the show. Elias promised that we would get a huge musical performance from him at WrestleMania, a performance that is 100% guaranteed to be interrupted by a legend. Maybe the Undertaker, maybe the Rock. Whoever it is, the Drifter will be left laying at the end of the segment.
Colin Jost and Michael Che of Saturday Night Live are the special correspondents for the show, which means we are probably getting another segment involving them and Braun Strowman. Strowman's terrible history at WrestleMania aside, this should be as short as possible. Hopefully, WWE does not add any more filler to this already long and exhausting show.
We all can only hope that we survive the endless barrage of wrestling that comes out way in less than three weeks, at WrestleMania 35.
