I was kind of excited, based on the initial leaked pics and whatnot, over the prospect of a really schlocky, Predator 2 on steroids (or, perhaps, Predator 2 on even more cocaine?) sort of followup. And I genuinely really like Shane Black as a filmmaker.
The film was probably more coherent before all of the reshoots and whatnot, but overall I think a lot of its major problems do fall on Black and Fred Dekker as well, in addition to the higher ups at Fox.
