How's the writing? One of the major reason's I've been hesitant to get it is because I'm afraid that the dialouge won't measure up to the original. There were no expectations with the first, with allowed the writers to do what they liked, but now that people are familiar with GLaDOS, I'm afraid that the writers are going to just write what the fans want to hear.
I hear there are no cake jokes though, which is a gigantic fucking plus.
