Well, everyone has an opinion on this. I don't know which game is 'better' persay, but I will say that I have already played RE5 more than RE4. MUCH more. The achievements were fun (just hit 1000 yesterday, which is rare for me), but it was the co-op that MADE the game for me. Its simply a great co-op experience. I imagine that most that don't like it don't have a buddy (or 2 in my case) to play through the game with, because its a MUCH different experience having a buddy by your side.
And to those that say it isn't scary, that's your opinion. Most games aren't scary, especially number 5 in a series where you've come to know what to expect. You're probably just jaded. But there were some moments that scared the bejeezus out of me and my co-op buds and we still get a huge laugh as we talk about those moments.
Lots of fun with the game and recommend it highly, but mainly to those that have the sense to play co-op.
