After reading Magic's SC storyline commentary and reminscing over the original and BW campaigns, I came to a profound conclusion.
Kerrigan sucks.
Seriously now

, IMHO, the Overmind was such an awesome character. From down to his voice, to his style of talking, the Overmind is just so much more of a menacing and awesome character. I mean, Kerrigan isn't anything to sneeze at, but IMO she makes the zerg seem too human. Her goals are power and killing the people who betrayed her, whereas the Overmind had a more cosmic plan, the perfection of the zerg and assimilation of all life. Kerrigan is a blood thirsty, ruthless villain no doubt, but the Overmind to me is so much more badass because HES NOT HUMAN, the Overmind in a sense, is almost like a force of nature, something larger beyond our scope of understanding, which makes him seem much more than kerrigan. (Did anyone else think it was blasphemy to have the overmind controlled by the UED? Or even try to bring it back in brood wars? Seemed just like another convenient way to make the zerg player in episode 6 to fight zerg+UED)
BTW, one part of the story which still doesn't make sense is why the hell the overmind would want to put itself on Aiur, that move to me looked like the designers way of making it "within the story" possible for the heroes to kill the overmind without traveling all the way to Zerus. Also his victory speech at the end of episode II seems to signify that they've won and the assimilation of the protoss was beginning, yet as Magic stated in the commentary, we don't see and infested protoss nor any zerg/protoss hybrids (methinks the designers got lazy), and if the whole point of assimilating the terran/kerrigan was to assimilate psionic potential into the zerg, why dont we see kerrigan on aiur, or any other zerg with the newly assimilated psionic potential? I feel that there are all these vast potentials which just got rushed over and ignored in order to make way for the episode three storyline. I mean, its like whenever you have an awesome character (Tassadar, the overmind, zasz, stukov, etc.), they have to be killed off (tho raynor seems to be the exception).
Another note, when I first beat the last level "Eye of the Storm", I had 12 battlecruisers, 12 carriers, and a whole bunch of tanks and dragoons (ok, I like those immature strategies, so sue me

), and contrary to what tassadar said, I had NOT sustained severe damage. Do you think there was any other reason why Tassadar had to die other than good story telling? And possibly because the Brood Wars storyline could not have occured if a badass character like tassadar was around? And shouldn't he be a grey templar instead of a high templar having studied with zeratul? Urgh......
