I do feel pretty positive for the film. Maybe this is some otherworldly threat that's hit Chicago and no Superman around, so this squad of expendables gets sent in...
The talk of reshoots is a little concerning, so close to opening day (less than four months away.) Reshoots are common in most films like this, but much earlier in post production. The timing is fishy, what with Deadpool being a critically loved monster smash two months ago - with all the humour mixed with gore perfectly balanced - and Batman v. Superman being critically decimated as a humourless slog and underperforming at the box office.
Coincidence?...I think not.
