The thing is guys, you're all taking this too seriously. It's called an opinion. I rather like Heroes and Thieves and think it is a superior album overall compared to her previous records but i'm not going to shout at someone for not thinking the same way. Just because we're fans of Nessa, it doesn't give us an obligation to automatically like whatever she produces.
I say, leave opinions to opinions. When someone is "disappointed", acknowledge that opinion but state your opinion too [and prefably in the fan reviews thread]. You can't say, "I don't see why anyone would be disappointed". It's synonymous to saying, "You can't have an opinion" or "you must like everything Nessa does, no matter what".
