they're utterly screwing trek lore and hostory up, its so sad. I still thnk they should have stuck to the "Missing" era and expanded it. that being the 75 or so years from "generations" to "TNG: Farpoint".
here we have a Known beinging and a known end and can build a ame that people can relate to and understand the story line. there's so much in that time that wasn't known, planets that were explored, races encountered, diplomativce problems still being hashed out (like the klinks still not 100% confortable with the feds, Romulan incursions and clashes, ect). Space was still small, ships were slower, so people could have taken time to explore and expand and discover all thsoe places that would soon be in TNG. then when the time came for a major expansion 3-5 years down the roads, they could jump it forward to TNG time, as we only know it from the Big D's perspective, there were other things going on too they could cover.
But just going after TNG makes no sense, is bad design and really doesn't lead to anything but an open ended combat design.
