10 Big Concerns Heading Into WWE WrestleMania 37

10. The Crowd Might Not React Well To Every Match

Say what you will about piped-in crowd sounds, but at least they don't result in that eerie hush that falls over an arena whenever a live crowd just isn't feeling the action.

This weekend's WrestleMania is the first time WWE will be hosting an event in front of a proper live audience (albeit a limited one) in over a year, so it's safe to say that audience participation is vital for the event's success. And considering how long the fans have probably been waiting to attend an event (let alone WrestleMania 37), we can be hopeful that they will cheer and boo until their hearts are content.

That being said, as you'll see as we venture further into this list, the match card for this year's Show of Shows isn't one of the strongest and the lack of build leading up to the event certainly didn't help matters. On that note, there is concern that the audience may grow weary with some of the less interesting matches on the card - be it down to lack of interest in the superstars, the programs or just any potentially dull in-ring action.

Understandable or not, that would be a major letdown considering how important the return of fans is to WrestleMania's success.
