^ TOS has a lot of qualities to it that requires patience and attentiveness, something the ADD riddled youth of today can't stomach, hence why most of the time they're the ones deriding it as crap.
There were a lot of people on the production crew of Star Trek TOS who knew it was something very special, something so compellingly unique next to everything else being made that day. And they exercised tremendous creativity and persistence because of it. It shows in many ways. Unfortunately severe time and budget constraints (and other obstacles) prevented the episodes from fulfilling their greatest potential, and so... it's easy to be unforgiving if you ignore all the good that came of them.
