Where do you start? Well, another vote for Babylon 5, my favourite programme of all time (well, excepting The Onedin Line, shut up) and also Farscape. Recommend Killjoys and Dark Matter too, though be aware DM died after season three AND it ended on a god-damn cliffhanger thank you network bots! Grrrr! Have to make my daily plug for Vagrant Queen, new and absolutely rockin, great humour, excellent world building, based on a comic series with some cool characters. Then there's Future Man (hilarious), Colony (another to suffer the axe after 3 seasons or was it 2?), another vote for Red Dwarf, also 12 Monkeys, Watchmen and Westworld, The Orville and if you're looking for a laugh try People of Earth. That's all I can think of for now.
