6. Star Trek: Enterprise Season 5

Despite a bland cast and a terrible theme song, Enterprise (rebranded Star Trek: Enterprise from season three) actually developed into rather a good show in its fourth and final series. Elements of the first two had been interesting and the show could be applauded for its season-long Xindi arc but it was year four that finally started to deliver on the premise of this prequel series with multi-episode stories dealing with Eugenics and the change in the Klingons, the spiritualisation of the Vulcans, the beginnings of the conflict with the Romulans, the birth of what would become the Federation and even an origins of sorts of the evil mirror universe. And then it went and screwed it all up by delivering a terrible finale that became a bad holodeck episode of The Next Generation instead of the focus on the birth of Star Trek as we know it.

But had the show not been cancelled - and that terrible episode written out of history - season five promised to continue the strong path of season four. Jeffrey Combs's fan favourite Andorian Shran would have joined the crew, and the first starbase would have been built as the founding of the Federation continued. T'Pol's father would have been revealed as a Romulan as the progression towards the war with Romulus began and we would have even got an origins of the Borg Queen with Alice Krige due to play a scientist assimilated by the cybernetic life forms. There would have even been prequel episodes to the original series with a visit to the cloud city of Stratos from The Cloud Minders in a three-part story and Flint from Requiem for Methuselah. And yes another mirror universe with evil Empress Hoshi.

Add in a refit of the Enterprise to make it closer to Kirk's original ship and Star Trek Enterprise season five would have had a lot to deliver. The questionable decision to do an origins of the Borg Queen aside it could have been another very strong year in what became the last Star Trek TV series to grace our screens...at least until 2017...
