A negative reaction from a subset of fans, sure. The critics haven't given it a negative reaction - metacritic is standing at 88% and top of the 'current PC games' list. A measly 7.5k end users have rated it, with the usual troll reaction user ratings often get on metacritic
You're right though, initial great sales could be due to the name. We'll see how things drop off over time and with expansions.
