Most Interesting Wrestlemania?

Hey Scott! What Wrestlemania has the most interesting backstory? So we're eliminating what you think is the best, or your personal favorite but the one that had plenty of missed opportunities, seemed mismanaged, and had the most backstage drama.

I understand the first one was quite a gamble, but I have to think 7 is a contender due downgrading from the LA Coliseum, the whole war baggage with the main event, and struggling to fill up a much smaller arena makes things very interesting.

Thank you!   

I'd say either 7 or 30 had the best backstory to them.  30 has had entire documentaries made about various aspects, so you could easily argue that's the winner.
