your list of things to watch
Babylon 5: if your going to watch this there are 2 things youl need to do and 2 things youl need to have...
to do: MUST watch from episode one, to the final episode IN ORDER. the story of B5 runs from episode 1 right through to the end and if you dont watch it in order, you wont have a clue, its not the type of show to catch here and there like trek was.
the 2 things youl need are, Time & Patience, youl understand the relevence of those words if you watch it
FarScape + Peacekeeper wars: same rules apply as with B5, plot runs from ep 1 to final, and then you have the tv movie, The Peace Keeper Wars...
Deep Space 9:
this show was slated a lot because quite frankly the first 3 seasons were pants, but watch it in order and bare with it because from seaon 4 onwards it was brilliant. although i wont lie, youl be rather annoyed with the ending.
Voyager and the next generation can be watched as and when you like, they are single story episodes, not too much of an order going on apart from the odd cast member being replaced and the odd 2 parter,
Enterprise: Season 1 = ok, nice plot running all the way through, seasons 2 and 3, Excellent, a long running plot, kept you hooked all the way, final seasons were back to the mindless wandering from episode to episode with no involving plot to keep you focused, just a new quick story each episode (people want to be dragged into a series and held there these days, Babylon 5 was in my opinon the first sci fi series to recognise this, it had an emense and complicated story brilliantly woven throughout the show
BattleStar Galactica (modern one) : you can catch up on this when ever but again the "watch in order" rule applies, fail to do this with any of the ones ive mentioned will result in you going "this is crap, i dont understand, im not watching it anymore" make sure you watch the 2 hour TV movie from 2003 before you start on the tv series, the movie sets the scene very well.
Enjoy
