So, after reading the preview and comments I noticed this:
The preview is mostly positive, but the only negative aspects he presented (and suitably backed up) were instantly attacked and a couple were worded in a hostile manner. Further, the arguments basically boiled down to someone presenting a problem, the critic addressing them/defended his opinion and then someone who didn't read any of the comments brought up the same issues... again... and then again. The critic is a M&B fan but was looking at it from the perspective of the mass market. Which as well know can sometimes be like a 10 year old on a sugar rush, that is, no attention span and a desire for instant gratification. And if the critic found some of the features lacking or difficult to figure out, then that shows incompleteness (which it is, still beta) and/or design flaws (which should exist still) and there's nothing wrong with either and both are present.
But before you open your mouths (or hands, rather) make sure you think about what you're saying and how other people will perceive it, because a game's fan base shouldn't be known as hostile children whenever their favorite game is criticized in any way.
