It just felt like they were preaching about that whole phone privacy crap that's been going on, and I think that, for current politics, if they want to monitor phones to help catch bad guys GO FOR IT, I sure know no one's going to care about what I'm talking about on my phone, and in the movie it's not like Batman was going to use it for anything untoward, just, you know, CATCHING THE JOKER. So it probably just bugged me because I don't share the same opinion as most seem to about the phone monitoring. For Fox to get characterization over that was just, idk, too little too late? But you're right, he does need someone to try and act as the limit on Bruce, it just felt really preachy to me.

(YES ORACLE PLZ. I keep hoping he's going to take in an orphaned circus preformer... XD)
