I'm telling yall that RE4 started the ruination of the franchise. It went back to the PS1's original cheesy ass story, it never was scary, and valued gunplay over survival horror. The characters were cheesy, the monsters were cheesy, and the bosses were cheesy.
Don't get me wrong, it was a fun game, it was just not a good RE game imo. If it was the start of a new franchise I'd be fine with it. Its just like Alien Res, a terrible entry into an established franchise.
RE5, and RE6 are basically just the formula for RE4 on steroids. The gameplay didn't really change all that much and the stories went further and further into the asinine territory.
