What Do You Think of RE5's Storyline?

The Resident Evil franchise has had it's lemons (i.e. survivor, and survivor 2). I want to know your reaction to the new claim that Wesker and Sherry are together. Mainly I want to know how she got there, when. Also do you like the main characters? I mean Chris and the woman of course. Personally I love Chris but i don't have the background to say I like this new character. Your Opinions please. No spam. No trash talk. Thank You
