The sets were rickety, a lot of the acting (but not from the principals) dreadful, the special effects were weak (particularly in seasons 1 & 2), the Centauri hairstyles laugh-out-loud funny the first time you see them, the dialogue often poor, and the whole thing had budget of £3.50 and a crisp packet! And yet I really don't care about any of that. Babylon 5 is quite simply the best TV series ever made. Period. A truly astonishing work of sublime genius, by turns hilarious, brilliant, tragic, thrilling, suspenseful, terrifying, gut-wrenching and joyous. The story! It's simply brilliant.
Weasel, if you've never seen it before you are in for a real treat! Please, please stick with it. Like many shows, the first few episodes find the show finding its feet a little, but if you're not hooked by halfway through the first season, I'll be very surprised indeed! There has never been another show that rewards regular viewing so highly. This is one story, one man's vision (J. Michael Straczynski), told over 5 years; a novel made for television.
And if you do love it (and I think you will), don't forget the various films that accompany the main series ('The Gathering', 'In the Beginning', 'Thirdspace', 'A Call to Arms', 'River of Souls', 'The Legend of the Rangers' and 'The Lost Tales'), plus the spin-off series 'Crusade'.
I wish I was watching it all for the first time again! I feel quite envious.
And if Frunkstar's link gives you any problems (although I'm sure it won't), drop me a PM.
Enjoy! :-D
