One of my absolute personal favorite TOS episodes is The Naked Time. But in order for the Enterprise to be compromised we have to believe three absolutely insane things
My favourite TOS episode is This Side of Paradise and it's hardly realistic. Still, I am more forgiving if an episode is more conceptual or ambitious than if it coasts along a generic formula. Most of my favourite Trek episodes (Such as In The Pale Moonlight, The Inner Light, The Visitor and City on the Edge of Forever) push the format in some way. I don't feel Abrams is doing this so it feels like the franchise is in a rut and to get out of it, I feel it must return to television.
The novel range seems to be doing quite well though.
