Reviews are opinions; unless there are solid facts that can be backed up to show something that's game breaking, it's merely one person's opinion of the game.
Now the fact that so many people are slamming it could be alarming, however, again, I'll reserve judgment until I get my hands on it and put it through its paces.
Part of me thinks that it's destined to fail in the sense that it can't please everyone. In other words, old school RE fans will complain that it's drifted too far away from its roots, while casual fans will complain that it's not a solid shooter compared to others on the market.
