Let's try to get away from the whole PC vs Console debate, which has been done to death in, and outside, of this thread.
Episode 2 was far better than I anticipated. Short, yes, but I knew that already. The adventure consists of "get from point A to point B", but the little things that pop in (spoilers aside, it fleshes out details on a lot of people) really help to expand the Half-Life universe. It seems, though, that I came out of Episode 2 with few answers and even more questions. Hopefully, one day, we'll all really understand what's going on, but that's not going to happen in the span of Half-Life 2.
