It's strange to me whenever anyone says "Modern Trek" and means "from 1987 on". I simply don't think of something that came out when Ronald Reagan was President, the USSR still existed, most people weren't online, and when I was eight years old as something that's "modern". I just don't. The '80s, in my view, are a retro decade. Period. The '90s are kind of a gray area. My definition of "modern" is roughly from 2000 on (give or take). For Star Trek, my cut-off between "Old" and "New" is the 2009 film because the Old Guard carried on until 2005.
