It's obviously not the worst game series ever, there are many series worse than CoD but I just think they're criticizing CoD for having a fan base of a lot of squeakers. I myself don't like CoD repetitive, yearly release games,(That means the minimal effort into the games) and gunplay(It's usually who ever sees the person first dies unless you're in like FaZe clan or some crazy crap like that) but I don't necessarily think it's the worst game series ever.
