"Remember when this series was about zombies"

This comment has always confused me when I see it on post, comments and forums like yeah I remember the zombies from the older title's. But the series wasn't about them it was about BOW's they've been apart of the series since the first game. Heck in the I guess you can say the umbrella era of the resident evil series you encounter more BOW's then zombies during the halfway point of the games. Not to mention how resident evil is and has always been called biohazard in Japan and it's because of these Bio weapon monsters that made me love the series in the first place always wanting to see what crazy monsters the next game would create. I don't know maybe I'm missing something.
