Super Mario 3D World is the most critically acclaimed exclusive of next gen (92.56% gameranking), followed by SSB Wii U (92.31%). Bloodorne is at 91.25%, which is 4th highest (behind Bayonetta 2)
Also, I don't believe that Bloodborne by itself is good enough to make the fact that "PS4 is great" the only valid opinion, like you claim. That's like saying that, because the PS3 has Dark Souls, it is inarguably a great console, and everyone who disagrees is ignorant. For many who don't like games like Bloodborne, and are not satisfied by the yearly instalments of COD/FIFA/AC/2K, there is still very little that the PS4 has to offer.
