It's definitely not for everyone, but it does as advertised. I can't remember the last time a game made me feel so alienated. It's just not for impatient people. Thankfully I haven't had any game breaking bugs.
A friend of mine played the Chris Redfield campaign yesterday (chapters 1 and 2; it took him 2,5 hours) and it looked like a good action game. The graphics were great and the action was basically like RE4 and RE5. Not sure where this 4.5 is coming from. Obviously just some personal grudge.
