5 is good if you do co-op. Single player experience sucked. Spent more time babysitting than enjoying the game.

6 got co-op right. You didn't have to share a single thing with the AI. The way it should've been in 5.

Imo, both of those games are kind of ridiculous. 6 was evidence that no matter how much capcom wanted to keep doing action games, it had run its course. Like, they ran out of ideas and just threw everything they could hoped it would stick.

7 salvaged and saved the series. Been a forward sprint ever since.
