So CBS is making a new Star Trek series. With the JJ Abrams reboots (of which I am generally a fan), there has been discussion about what counts as valid or real Star Trek.
TOS innovated, but it wasn't necessarily Star Trek truly at its best. Occasionally it had some moral dilemmas, and good character interactions, but it also frequently fell in the realm of camp. But it was a low budget 1960s series.
With TNG it really hit its stride. It built upon some of the work established in the better Star Trek movies and moved it even further.
We had some episodes of truly great sci-fi writing, though this was still before the DVR and Internet eras, so the universe had to return to the status quo at the end of most episodes. You couldn't have lengthier, more complicated plots for the most part (save for some excellent exceptions like Worf's backstory).
The reboot movies have screwed up one thing, and it wasn't pandering to the masses or making entertaining action movies. Honestly, that is fine. Their failing was being inconsistent in its own universe. You can teleport at warp to a moving target at warp because the story calls for it in the first reboot, but you can't teleport Spock who is falling into a volcano because it would hurt a dramatic beat. They have to be careful that they do not treat technology as fickle and inconsistent magic (one of the failings of Doctor Who).
But most important, we need a return to this.https://www.youtube.com/watch?v=Xh_t2fFF3B0
