Community reviews will always be a mixed blessing and tend to skew towards the extremes. I see the same with extremely positive reviews as well. They seldom paint the whole picture.
In any case, I personally dislike review bombing in any direction, but arguing against them is pointless. I understand that people are frustrated by quality issues and in this case, prioritizing other teams with people from the I:R team I get that, I feel that as well.
But personally I try to distance myself from that when reviewing the product, as I really enjoy the game. Yes I would love to see more fixes and DLC, but I really love the game for what it is right now as well. That is currently all that matters to me regardless of what I feel about the business decisions of PDX. That is a separate issue for me.
I bought it with what it is in mind, not primarily for what it can become. Things can happen, plans change, and if promise had been my primary concern when buying, I would have waited longer to see how things panned out.
So bomb away, it's everyone's prerogative. Personally I don't like it, but that doesn't count for much in the end.
And also, yeah, the Leviathan debacle is probably a factor in the reactions we see here. Something obviously happened there, but the tone is already changed after yesterdays patch. I know that PDX has gotten flak for their policy, but the seem to genuinely want to fix things with I:R 2.0 and a couple of really quick patches from Tinto (Midnight shifts obviously) to fix Leviathan.
Obviously lessons should be learnt from all this, but as I always say; don't buy games on promises, no matter who is making those promises. Buy stuff for what it is primarily.
