Why do people enjoy RE4, but despise RE5?

People enjoyed everything about RE4 but there were a lot of criticism towards RE5. People called it racist (I know it isn't), too action-y (no survival-horror), and has a weak story. Ironically, RE4 has those things too. You kill Spaniards, it was a save-the-damsel-in-distress type of game, and the story: Leon works for the government, has a mission to find the president's daughter, and coincidentally encountered infected villagers that have nothing to do with the Raccoon City outbreak, B.O.Ws, or Umbrella. How is that relevant to the Resident Evil games/story in any way? I know what some of you might say that the reason RE5 was a disappointment is because there wasn't much change and felt the same of its predecessor. If that's true, why were the clics like RE1, 2, 3 and those before 4 had so much praise? They were all the same type of games: go to a room, can't move the camera, shoot zombies, and solve puzzles. Now back to subject why do people hate RE5 for the things RE4 has too. Do Resident Evil gamers want repetition or variation in the games (or future RE games)?
