Just a great final scene. I would say one of the best final moments in all of trek, up there with Picard and his flute (different tone entirely).
Some people crave a sequel or more info on the station, but I like this as is. No more information, keep it mysterious.
However, I am afraid the station will be luring more people to replace its damaged "processors". I wish Enterprise had known it repaired itself and left a warning beacon - but then, it is horror.
