I think it's completely fair for this game to be poorly reviewed based on the mediocre gameplay, poor script, and lack of content. Actually, it's a big improvement from a few years back when games were highly reviewed nearly solely based on hype and AAA budget. This game has a lot of shortcoming, and it's a good thing to point them out.
But the petty insults, name-calling, making fun of passionate and talented -despite a few bad decisions- creators, ... we are bullies, aren't we ? This whole backslash has really showed how very immature and childish many players - and even some professional journalists - really are. It's really shameful.
