Okay the final showdown being a game of manhunt is a nice way do things. Definitely seems way outside Mackey's normal MO but he's stressed and pissed off, and it's good writing. So I will happily buy in.

This also let's the climax be much faster paced than the mystery stuff. It's a nice change of pace. Not that i thought the mystery stuff was slow. But I think another abduction scene in the middle would have been a good idea.
