Things that bug me(nitpicks, I guess)
In the subway, once the bomb had mixed, why did John leave the case open and stare at it instead of just closing it up and running?(very minor)
Also in the subway scene, why did Simon even bother calling the payphone? Not only is it made clear he had given them a task that was impossible in Simon's eyes, but the bomb was shown to be triggered by contact between the train wheel and the rail. That means Simon had no chance of stopping it even if they did show up. That makes the phone call even more bizarre, and further more, wouldn't that bomb trigger have to be placed on the rail between trains arriving and departing within the previous few minutes so a different train didn't trigger it?
Speaking of that phone call scene, what exactly was that cop doing? First of all, I'm quite sure cops don't pull their weapon out on unarmed men who simply jumped the subway turnstile. Second, what the heck was he doing? He just stands there pointing his gun at him saying "hands up!" but never calls for backup or attempts to cuff Zeus. It makes no sense.
