If you were going to delve into some the tv series, there seems to a be general Trek TV rule (TOS withstanding of course)
that it does not get good till SEASON THREE!
NEXT GENERATION -- With the exception of the 2 part pilot, seasons one and two I find almost unwatchable. Alot of horrible episodes when one looks back now.
But by Season 3, they had a solid stable of writers and a clear direction for the show and its characters. Until Season 7 that is, when most of the best writers had moved over to DS9, and then the show began another downward spiral. Though the final 2 part episode "ALL GOOD THINGS" is absolutely brilliant.
DEEP SPACE NINE -- A more solid start than NexGen, but it took almost 3 seasons before the writers had a clear handle on the direction they wanted for Sisko. And I disagree with those who claim DS9 is a rip off of Babylon 5 (another show I LOVE!!!), yes they are both set on space stations and deal with epic battles, but that is like saying all cops shows are rip off other cop shows. In my book, DS9 is still the best crafted, acted and written of all the Trek series.
VOYAGER -- I don't like it. But even I will admit, the show improved with the addition of Seven of Nine in season 4. But soon, even that wore out its welcome.
As I said before, after watching Trek for 25 plus years, Voyager just felt tired and unoriginal in its storytelling. However, if Voyager was your FIRST Trek experience, I can see one enjoying it a lot more.
ENTERPRISE -- Love and Hate all at the same time. I give the producers kudos for attempting a prequel and experimenting with different storytelling styles. But again, the show just did not seem to gel until season 3. Season Four, is wonderful as new producers took over and almost every episode is a true "prequel" to other Trek episodes, significant universe building was done in this last season.
To Boldly Go....
