I never actually saw the movie, but I gathered from the trailers and reviews that Abrahms threw more sex and action scenes into the formula to get more young people in the theaters while downplaying the contemplative and philosophical elements of the series. This is what made Voyager and Enterprise inferior to the previous three shows.
One thing I am curious about: I understand that some sort of time traveling mishap changed the backstory of the original series and created a whole new timeline. Does this mean that the original Star Trek universe has been replaced or is it supposed to still exist in a parallel universe or something?
