User reviews on Metacritic have fallen into a familiar pattern. People who hate Sony, MS, their products, the devs. etc. for whatever reason vote 0 and effectively cancel the votes of fans who vote 10 because they know this happens. For a game reviewed at 9 one hater cancels out 9 fans so the results are skewed. An honest effort with a score of 7 or 8 is rare. EA haters and the broken free dlc system would account for some of the discrepancy on ME2.
Hope Sony and Zipper can iron out some of the issues here as the scope involved will force the online systems to progress. Lag, maps and player experience problems can be fixed.
