Trek 'purists' may be a bit put off by the alternate timeline theme, but it gives Abrams & Co. the creative freedom to boldy take the franchise where it has never gone before. It took a while to warm up to the new cast's portrayals of our familiar heroes (& heroine), but, by the end of the film, the characters were sufficiently well-presented to launch a sequel. IMHO, Karl Urban was the best of the trio as a somewhat more eccentric "Bones" McCoy. All in all, this was a great re-imagining of the Trek universe. If you avoid the pitfalls of conventional Treklore, you will really enjoy the story as it is told from a fresh perspective.
