I can't imagine why anyone would want to go with a generic cover. Christopher asked, but I am assuming by generic you mean something so obtuse that it could apply to any of the Trek incarnations. The book is clearly TOS, and with that in mind, I like this cover. Enterprise gives me the time period involved, and the other ship along with the planets gives me the 'wonder of space'. The colours used, especially after seeing many Hubble photos, does the same thing.
