Unfortunately, there has been a number of ingress points for wildlife into the Centre so I would not be surprised to find out that there already is a healthy amount of excrement in the southern end of the retail part of the mall.
I'm guessing folk in corporate AMC wish they could get a do-over for the renovations and contract extension they did. I'm also guessing their legal department is going over that lease for any way out (if they don't have one already). The Park Place Outlet Mall does have a big chunk of 'entertainment' space listed in some of its earlier site plans. Might work well to have AMC move there.
