Seriously, the game is getting plenty of positives. Gameplay and the content that's there seems to be getting a lot of praise, it's just that the amount of content at the moment is too small to ignore. Reviewers are not telling people to cancel their pre-orders and stay the hell away from the game, they're simply saying that the available content may not be enough for everyone. If you feel like there's enough game in there to justify a Day 1 purchase then that's fine. I have the game pre-ordered and I don't feel like I'm getting robbed or anything.
But it's beyond silly to complain about reviewers not taking into account future DLC that they have zero experience with, just like it's silly to focus only on the lack of content and ignore everything else that has been said in order to label the game as some kind of act of thievery.
