*stands up and applauds*Isn't this the whole point of different series?
Generally speaking (VERY generally) it would help to enjoy religious, political, or dark science fiction if you like DS9.
If you like Klingons, read the Klingon Empire books.
If you like the idea of a single ship, cut off from home, read Voyager books.
If you like the original "strange, new worlds and new civilisations", read Titan.
If you like history (that's a broad term), or the idea of the "start" of the Federation, and humanity's first forays into space, read Enterprise.
If you like comedy, classic adventure, characters with attitude and a wild science fiction imagination, read New Frontier.
If you DON'T like any of the above themes, don't read those particular books.
Saying you like Star Trek no longer has the same meaning as it did 40+ years ago. Star Trek supports so many of its own genres and themes that it requires a little specificity. If I said I like films, that doesn't mean I like ALL films.
One of the greatest things about Star Trek is that you can pick and choose your series based on what you like. You shouldn't automatically expect to like every series in Star Trek just because you like Star Trek. And there aren't any rules to being a Star Trek fan that say that, just because you are a fan, you MUST read ALL Star Trek books.
Well said!
