My response to concern on length is always to look at Journey. I'd pay $60 for that wonderful experience any and every time. Perceived value is up to the individual. There are times where there is legitimate concern and the game stops you from actively enjoying it in terms of bugs(looking at you ACU) and people need to know, but most times these days, in relation to this genre it comes down to what I think is a stark difference in preference.
Reviewers should, I think, tell us if something does what it does well, but too often they confuse success and competency with their own enjoyment. A lot of these reviewers have Platinum games releases in their top ten list, usually indicating that they are more traditional in taste.
To be completely honest, I cant stand the Souls games. I think frustration for frustration sake is a stupid notion and I don't get any validation out of fighting the same boss for an hour and finally succeeding...
That said, those games excel at what they do and are a needed addition to a medium that has perhaps overall placed difficulty on the back-burner of importance. I don't think I would like Bloodborne at all but that wouldn't change the fact that it could be a fucking great game. I wouldn't be the right man to review it because I already don't care for what it represents. I'm not saying this is done for The Order, and for all I know it may yet be deserving of the scores(I really, really hope not) but it feels like some people are bringing universal expectations to games that they no they wouldn't deliver on. The Order was never going to be anything but linear, I don't need to know that in a review, I need to know how well it did linear.
