You do hyperbole.
The original series had 80 episodes. I am afraid to know the high fraction of the posters here that have seen them all.
As for the other series:
"the safest way to travel", according to dialogue in the Star Trek: The Next Generation episode "Realm of Fear".
The things you can learn from wikipedia.
The only mortal failure I know of was that seen in the first movie. I think it was put in so they could show them docking and undocking and flying around in shuttle craft. Which they did not want to do on the first series. So it pretty much always worked, except the few times some writer wanted it no to.
