Yeesh. I thought it was witty and funny enough to keep it going. Obviously it is a little difficult to build a character around what is essentially a form that you never see (Glados), and Wheatley had some good lines. I particularly liked early on when you are trying to solve the one puzzle and he is way up in the ceiling talking to you, but you only catch a small portion of what he is saying. It goes to show you that he really is just dumb as a rock and doesn't really notice nor care for you that much. I don't know what you guys wanted aside from a bunch of puzzles to solve in silence. :lol:
That being said, Cave Johnson was possibly my favorite from the game. "I punch those numbers into my calculator and it gives me a smiley face."
