Somewhat different from the final script loved by fans, but interesting to see the original, especially as a graphic novel with touched-up photos of the original actors added to the drawn figures. The biggest plot difference is that McCoy is not the catalyst for the changes in time or the climax, and it was a much more emotionally-satisfying touch than having an unknown crew member cause all the trouble. No emotional end with McCoy confronting Kirk with "Do you know what you've done?" and Spock responding....well, if you're a Trekkie, you know how that went. ( )

If you like comics, or just like to look at good photos, you;'ll enjoy this one.
As far as a story with meat goes ... it's an adult comic book. ( )

Back in the late 70s, before home video was widely available and Star Trek was off the air, these books were like gold-dust and highly sought after! As a result sets were hard to come by and commanded a ridiculously high price on the trade paperback market.
Since their true value was in being able to 'view' episodes on demand; and with the introduction of cheap home video, Satellite, Cable networks and more recently DVD box sets their value has plummeted to almost worthless levels.
Five stars - in honour of their previous services. ( )

Probably one of the best original episodes. McCoy goes through a time gate called The Guardian of Forever, and disrupts history, making the Enterprise and all aboard her nonexistant. Kirk and Spock must follow him into the past and undo the damage - at a cost neither of them expect. ( )
