So, I'm about halfway through the second episode, and so far I am digging the hell out of this game.
The first trial with Mia was a lot more involved than I thought a tutorial chapter would be, and young Phoenix was quite hilarious. I've heard WONDERFUL things about the fifth episode, too, so there's that to look forward to playing.
Let me add to the mounting kudos. I am not a huge gamer, usually only bothering with sports titles and the odd thing that catches my eye, but I am diggin' this bigtime. I really think they captured the feel of what it is like to BE Batman.
