It's your opinion, and you're free to it. (Of course, I'm sure the story and characters would call it a wrong opinion, but c'est la vie.) If the name is all that survived, though, surely you wouldn't keep buying the game. Since it sucks now, by your count. Or would you?
The story and characters are as superficial as the name. Interestingly enough, if they had removed the story references and changed the characters of 4/5 (and item names too, I suppose) it would be virtually impossible to draw a connection to the earlier titles. Hardly appropriate to say it "survived."
And for the record, I never bought 5 and have no intention of buying 6. I did buy 4 unfortunately, only because I was unaware of the crapfest it would turn out to be.
RE4 was really fun. RE5 was fun too if you are playing co-op with a friend. Though I like Dead Space 1 and 2 far more than RE5. I've heard Amnesia is a great horror game. If you guys are so sick of RE then try that out instead. Better than complaining about a game that you stubbornly hate before everything is even known about the game.
RE4's story was irrelevant to RE's overall story in alot of ways, but the series had to adapt. I've been a fan of RE since RE1 on Playstation, and sure I miss some things, but RE4 overall was more fun to play imo. RE6 has Leon's story being more horror-like. Looks RE to me.
