One for the fans, as it just expects you to remember everything. It also “closes” some of the threads left open from IA 1 so it's worth seeing just for that.
But I was disappointed, it is a bit disjointed and confused - although some of the confusion is on purpose so you don't know who will be the good guy in the end.
