I said I like Bab5... but watch it again some time... not only is the delivery of dialogue often awful, but not once when you see a frontal shot of a whole person do they look natural, they're always stood bolt straight upright... B5 is one of my fave series, but not because of the acting, and the number of re-writes dues to actors leaving and being replaced meant that the plot does get a touch sketchy in places. B5 is one of my favourite sci-fi's possibly one of my fave shows, but, you'd have to be blind, or maybe dead not to notice the "quirks"

And the actors in Farscape never once look un-natural, and the dialogue is delivered well everytime... it has more character development than any other sci-fi, it has more emotion than most, and it does what only a very few sci-fi series bother to try, which is to make people seem like people... in most others everyone is a stereotype and never once tries to seem normal...
