I tend to desagree with Malaika. I think a clean and independend reboot would have been easier accepted by the so called "Hardcore Fans", than this soft-pre-se-quel-reboot. Because the JJ-Boot is so undisicive, weather it is a continuation, or a new start over, the forums around the globe are filled with people trying to make heads or tails of it.
My Point is: would Star Trek: Star Trek 2009 have been a clean reboot - a new ship, a new crew with familiar features and names - the fans who did not like it would have had the opportunity to say: I don't like it, but people who like it are welcome to. I have my own Star Trek. (Of course, the debate would have been about which of the versions was the REAL Star Trek.)
But the JJ-Boot utilized the Prime Universe and changed it. So it became impossible to say "This is your Star Trek - and this is my Star Trek" because it is (according to the storyline of the 2009 film) the SAME Star Trek Timeline.
With a clean reboot, one could have explained every difference between the now shown and what was on the old TV Show. They could even have completely redesigned Klingons and Romulans and Breen... Including their backgroundstories
I think by trying to eat the cake and keep it at the same time, the KLO Team wasted a chance to really rid themselfes of the balast of the old storylines AND create a brand new fresh and original universe around the caracters. (That is at least their explanation why they wanted to soft-re-pre-se-quel-boot.)
