I don't have any difficulty in believing it to be the real burial cloth of Our Lord Jesus, but if it is, my problem is with many of the revelations about the Passion. The ones I have read say the scourging for instance was similar to the Passion movie and even worse, but it doesn't look like that at all in the shroud. The wounds look less severe.

So either the revelations are wrong and mistaken, or the shroud is not authentic, or maybe God made it so the wounds look less severe in the shroud, I don't know this is what goes through my head.

The wounds were lovingly cleaned and bound before he was wrapped in the shroud. Even so the shroud shows scourge marks all over his body, puncture wounds on the scalp, and of course the stigmata.
