I'd complain that it didn't actual fly around and use thermal imaging to track my enemies.
And it didn't ATTACK! The crew and even SSC's product development ooh'd and ah'd over how it could not only track, but also attack. Yet we didn't get more than an ounce of falcon attention. I also wish they showed more interaction between Falconer and his machine and between Tracker and his dogs. Ah, well... maybe we'll get it in the inevitable super-huge unrated collectors' edition cut.
