Personally the most bored I've been while playing a RE game. I cannot talk about RE6 as this was the last straw for me, but think about everything you like about RE4, and imagine a game that doesn't do anything to improve on that formula, but worse, sometimes it managed to make a few steps back:

Core gameplay is the same, visual are worse, barely looks like an horror game thanks to the generic pìss filter, co-op was unnecesary and broke immersion, partner's AI is braindead and vastly inferior to Ashley (at least you could put her in the Trash where she belongs), weapon shop has no charm, it just appears at the end of each chapter out of nowhere, the inventory system is barely put together and extremely limited, the gore is abysmal, might as well not be there, most weapons feel generic, the turret sections ruin the pace of the game, they happen during some bosses too, which are mid at best, the stupid quick time events during cutscenes are still here for some reason.

Seriously, I'm struggling to find something I could call an improvement over RE4, I guess a prompt for attacking downed enemies? I'm really scraping the bottom of the barrel here, since this is something one could do in the previous game as well w/out a prompt. Let's be honest here for a minute, the few people who overhype this thing like there is no tomorrow aren't exactly RE fans, they're mostly meatheads coming from CoD or whatever other game looking for some couch co-op in an era where every videogame was a carbon copy online FPS, heck even the developers themselves admitted they wanted the Call of Duty audience so, yeah... good for them. Now they're gonna remake this and who knows wth they'll cook, not looking forward to it. For any actual RE fan, you'll most definitely have more fun playing the previous game.
