Nah, he's pretty nitpicky -- when you feel the need to make the disclaimer about it not being geeky nitpicking... then it probably is. And it is. Despite his initial disclaimer, almost none of those things are something your average player would spend two seconds thinking about as they played through the game. They'd just enjoy it.
Which has generally been my experience from observing others.
I gave some good examples from the review.
The caliber of writing for Wings of Liberty was quite disappointing. Never mind that characters don't even speak entire paragraphs anymore. The eloquence of the broader vocabularies they used in StarCraft and Brood War were superior to what they use in Wings. It really gave the world substance and believability which is vital for fictional worlds, etc. I had many issues with Wings given how much I enjoyed the story of StarCraft. Sure Brood War had a plethora of its own issues, but none so gaping as is evident in Wings.
First and foremost was the failure to convey what they intended with the Overmind. I was noticeably upset as well when I reached that part. However, I don't really hold it against them only that they blundered in conveying the message. Brian recently even noted that it wasn't a good idea for Tassadar to compliment the Overmind after his whole resurrection thing.
Moreover, I never could understand the examples I gave above. Arcturus' use of media was counterintuitive to his objectives. Honestly, Donny and Kate were bad for Arcturus' image and I must admit so were those hologram images of Arcturus spreading propaganda that was also counterproductive to his agenda of conveying to his people that he was a just ruler. However, unlike the review I do not believe this is an issue.
If it was on Korhal, it would be an issue. However, those holograms were only seen on the fringe worlds where only a portion of the Dominion's people lived. The majority lived on the core worlds. I find it a flaw in the logic of the reviewer given that it was pretty obvious that Arcturus had no problem revealing his true colors on some of the fringe worlds' inhabitants. With all his power it would be easy for him to monitor any travel to those world, that way he could cover it up.
Besides, there was graffiti all over the Dominion billboards, etc. which meant that the people were already at the point of rebellion. Squandering all the credits he had pursuing Raynor though shouldn't have been something broadcast on the UNN. Back on that topic, Donny sounded like a baboon trying to cover up the things that Kate slipped up, or otherwise intentionally said. Realistically neither would be employed, or still breathing for that matter.
I disagree with the reviewer's sentiments on the Korhal infiltration as well. Raynor is resourceful and this would be a key opportunity to prove that. This was too apparent throughout the duration of the campaign though, but I could realistically see him pulling off the Media Blitz's mission. Although his partnership with Valerian and relationship with Tychus could have gone with a little more exploring. I was curious why Raynor did nothing after Matt informed him that Tychus' suit was a deathtrap.
Kerrigan is another story entirely. She wasn't all that competent whatsoever. Even on Brutal the atmosphere didn't change enough to really feel threatened by her. Kerrigan just made empty threats and never met with any success in spite of having the strongest force in the sector. Then there was Nyon and his Tal'darim brethren.
He was made to be far too generic. I thought Nyon would have some interesting side story that ran concurrent the main plot, but he and the Tal'darim just popped up when Blizzard needed some foe for claiming the artifacts. Ironically Kerrigan only shows up when you attempt to take the first artifact. Wouldn't it have been more likely that you would have fought both Tal'darim and Zerg trying to claim the artifacts?
There was potential for Nyon, but that was overlooked. Valerian's relationship with Raynor also felt most rushed and the music seemed to grow over the top at key moments and so did the cutscenes. The sun shining through the clouds and raining on Char was a bit much. On a volcanic planet I'd expect that to more likely be acid rain. In which case it is not a good idea to be sitting around in it.
I hear the book Flashpoint really elaborates on the relationship between Raynor and Valerian, but it would have been nice to see a little of it in Wings aside from how rushed it felt. Another clarity issue was with Raynor's mood swings caused by the nonlinear plot and his lack of internal conflict. Blizzard said that he was conflicted between saving and killing Kerrigan, but we never see the side of him debating killing her which would also have been the opportunity to mention Fenix whose lack of reference upset many people.
