1) Thread drift happens. Get over it.
2) Opinion. Everyone has one. Get over it.
3) See 2.
4) "It's all there" implies that there is no more to Khan's motivation. The existence of Space Seed, whether you've seen it or not, is vivid proof of the opposite being true, as an absolute. And, people chime in on conversations here all the time. Get used to it.
I understand thread drift. It doesn't change the irrelevance of your post.
I don't need you to explain to me how a message board works. Repeating "get over it" over and over again is defensive and unnecessary. I challenged your post, but it wasn't personal. If it felt personal, that's on you I'm afraid.
Regardless of your opinion (and indeed everyone does have them, which just goes to show how valueless they are), my own experience indicates that your position is inaccurate.
So not only was your post irrelevant to the primary topic, irrelevant to my response (that was not directed at you) and inaccurate to my experiences (I had no problem whatsoever understanding Khan's "motivations," nor has anyone I've ever shared the experience of the film with as their first exposure to the franchise)...for some reason you got chagrined as well.
I'm not in any way arguing that the experience of watching TWOK wouldn't potentially be ENHANCED by having seen Space Seed first. I'm arguing that not seeing it in no way deminishes the effectiveness of TWOK as an entry point for Trek virgins.
Which was the point of my posts. And the point of this thread.
Now, is there anything else we need to discuss to satisfy our need to defend (unintentionally) bruised egos, or are we quite finished? "Get over it" indeed.
