We can judge the game on two levels...
Claims to be canon: Gearbox have been so incredibly loud about this - including on the most recent video - that making simple observations about the sheer number of things which contradict canon (after watching almost two entire missions through, no less) is a
perfectly subject for legitimate for discussion. You don't want that to trouble you? Well, nobody's asking you to.
But effectively telling people to stop talking about it isn't very constructive, either.
Bottom line is that Gearbox are the ones who keep bringing this up.
Gameplay/entertainment value: After seeing the afore-mentioned almost two entire mission's worth (and various instances reflected in the advertising), discussing how entertaining/atmospheric it'll be, is also very much a legitimate subject for discussion.
And let's face it, we wouldn't be fans if we weren't able to make fun of how our own fandom is being represented, like I did
here, would we?
That's what separates us from the scary obsessives...
So long as criticism is constructive, there's nothing wrong with it. I've made observations on stuff I've found strange, but tried to qualify it with how it could've been done differently/better. I've
also said that I hope the game will be enjoyable as an experience. But I'm not going to lie and say it looks any different from the '
Doom' formula or the 2010 AVP game, because it doesn't.
Just like how I still disagree with those who say the Alien or Predator are incapable of being scary/formidable on film, any more. The problem's never been over-exposure. It's that they haven't been portrayed right in ages.
