You cannot use metacritic and gaming websites as an accurate litmus of how games have been received by the entire community. Inquisition probably sold somewhere around 2-4 million copies based on the previous two installments. Out of those 2-4 million people, probably 5-10% of them take the time to go online and write about their experiences with the product. Forums vel sim. tend to attract individuals from polar ends of the spectrum.
Claiming that the game is a failure and widely detested basd on the opinions of friends and family isn't any more reliable. Does your extended family comprise the 4 million people who purchased Inquisition?
As for the "glaring flaws," as I've said before, I'm perfectly willing to admit that Inquisition has it's share of problems, as all games do. For me, that is not a deal breaker, for others it might be. It all depends on what you place importance upon.
I think Gothfather's post was quite reasonable. He/she was merely saying that, just because you personally do not like a product does not mean that you have to embark upon a holy quest to prove that everyone else who does like said product is wrong.
And yes, claiming that GameInformer, IGN, Electronic Gaming Monthly, Hardcore Gamer, Gamereactor, Ars Technica, The Escapist, Polygon, and the dozens of other gaming websites that voted Inquisition game of the year were all bribed is ridiculous.
