I agree with everything here, Portal 2 is awesomely awesome but it left me with a bitter taste because the ending song sucked. I was totally expecting a worthy sequel to Still Alive and it ended up being an insult to its memory. Other than that, the game dragged a bit in the middle (the Cave Johnson part), but it's still gonna be prolly the best game I'm gonna play in a long long time
Though I've only heard Want You Gone once, I don't really wanna hear it again
