This is an ongoing series of fan made Star Trek stories. Set in the TOS time, this covers the period between the end of TOS and TMP, covering the remainder of the Enterprise's 5 ive year mission.
The sets are very impressive, so impressive, that Paramont, I think, even borrowed the sets, owned by Mr Cawley himself (kirk) for use in the Enterpise season 4 story "In a Mirror Darkley" for the Defiant scenes. Add to that the past guest stars from the Trek shows, like George Takei and Denise Crosby, it makes it even more fun. Some of the stories are from the unused Phase 2 scripts for the Phase 2 series planned in the late 1970's.
I think this is a well made series, and prefer this to JJ Abram's......thing....that has the Star Trek name we got 3 years and and the monstrosity for next year.....this is more akin to the Trek I remember....and want to see more of, not more junk from the guy who made Lost, which I felt was also bad. Even Mr. Cawley himself talks smack of the JJ film as well in a few of the videos on Phase 2 YT channel.
Here's an episode to enjoy, there's more on the channel.
