Alternate timelines mean there are no paradoxes. Paradoxes require a single, unbranching timeline.

Call it a paradox or call it what it is cheap story telling but taking into account the effect of Kirk's fathers death would have on Star Fleet assignments and rosters and the effect it would have personally on Kirk what are the odds the exact same crew would end up on the deck of the exact same star ship? There's you basic definition of a paradox, a situation which defies intuition. As BatesD pointed out you have to resolve a disruption of the time line due to the devastating effects it has but in this time line it made everything work out perfectly? No paradox. Give me a break.

There is a complete back story to everyone of the characters in ST:TOS but they couldn't deal with any of that so they had to throw them all onto the frickin Enterprise straight out of the academy and put them all into there exact same positions before they day was out. The characters are the franchise (otherwise it would be simple enough to put another crew on another ship and tell there story) and in this generation of instant gratification you better do it now or the audience ain't gonna be happy. It's the equivalent of Lucas saying, "Actually let's make it that Anakin isn't really Luke's father...oh yeah... and the Clone Wars never happened."
