Pretty much agree with what's been said up stream, I did find the machinations in Dredd a bit tricky to follow, everyone in the dept in uniform looked similar (with one exception white, male, older) a better mix of race, hair cuts and body shapes may have made it easier to follow, or even the handy BIG name badges prominent.
Perhaps if the Psi Judge was introduced in the first act? I like the idea of a chain of random events leading to the Batgilder's demise too.
