34 Hours later, Mass Effect 2 Finished

These last three days I've done almost nothing but play Mass Effect 2, which is both awesome and rather sad at the same time. I've completed the main story and probably 80% or more of the side quests, so I think I have a representative sampling of the game at this point. Since I'm about to start writing the review draft, I don't want to talk about it too much, but I'm really of two minds on the game. In many respects it's a massive leap over the original. Yet at the same time, there are a couple areas of the game I consider major disappointments. The text for the review will convey my feelings well enough, but the tricky part is going to be how to quantify those feelings into the magic score, which is realistically the only thing 75% of people are going to look at anyway. How hard do I ride this game for its one great flaw, in the midst of so many positive attributes? I haven't decided yet, but considering this flaw was supposed to be one of the game's biggest strengths, I'm leaning on side of a heavier deduction.
