It's a very good game, but a bad Resident Evil at the same time.
A good game overall because of the graphics, gameplay and sound. Bad Resident Evil because there's too much action, no zombies and no many scares. And I also miss the claustrophobic environments.
In the past RE games you walked through small hallways or other narrow environments. Those situations always gave you the feeling of being trapped and there's no where else to go. The "I'm fucked" feeling. I seriously missed that in Re4. And you just have too many bullets in Re4.
The regenerators in Re4 are brutal though. Scary mofo's.
