It's not very fair to compare a companion from an expansion to one from a full game that got a full arc and character quests. Of course Awakening Anders was more shallow, you don't have time to dig more into it. Also, I actually appreciated a more shallow character in this world that is always filled with heavy heavy characters. The point is, Awakening Anders is someone I would have liked to get to know more because there had got to be something that made him the sarcastic self-preserving way he was. We never got to find out in DAII since they rewrote him completely.

It's fine if you prefer that character from DAII called Anders than the one in Awakening called Anders. But they aren't the same person.
