The Resident Evil series by Capcom is extremely profitable for them, hence why it gets milked like heck.
The franchise as you know started life as predominantly a 'survival horror' game. It was to become an icon of the genre and a lot of similar games by rival companies had been released to also make money off of its popularity at the time. However, as the series grew older and appetites changed, the series basically became Call of Duty with horror elements, and then the term Action Horror was more or less coined by the fans.
Resident Evil 4 was so unlike the games before it, but at the time, nobody really cared. Shooting everything in sight was more fun than ever, and you could sell treasures to the creepy merchant and unload on the monks and monsters some more. It was new and very excellent, but a horror game it certainly was not. Well, not really anyway. Then RE 5 strayed even further from the formula of old. To me, it felt like Sheva was just a "filler" character for Jill Valentine, even if yes, Jill was a supporting character in RE 5 and later playable in the DLC extras. And Wesker was just so unlike the Wesker I grew up with, like in the days of the RE remake, Code: Veronica and The Umbrella Chronicles. If they were going to face him and kill him, they should have at least brought back Barry and maybe had Leon in it as well. It just seemed like a wasted opportunity.
RE 6 is a game I wanted to love, but the game-play each year just seems to get more horrible. The older games also got criticized over the tank like controls, but at least they were something you got used to. Now you have interactive cut-scenes and all this stuff.
By the way, who here likes the movies with Alice?
