I think the writing is fine, but the padding is just awful. Yes, it was an issue in Wings of Liberty too, but I still hate it. You remember how in the original StarCraft & Brood War each campaign was 8-10 missions and every single mission was connected to the plot? Well, say goodbye to that. Now most of the missions are just MMORPG styled fetch quests to pad out the game with the plot missions scattered haphazardly around the game. The story is good when we get to it, but I really wish the campaign was shorter and more tightly focused.
