It's been over a decade since Doctor Who stormed back onto our screens, bringing a fresh batch of sci-fi and fantasy shows in its wake.
But 11 years later and Misfits writer Howard Overman has told Digital Spy that it's once again "a real struggle" to get these types of shows "off the ground in Britain".
"We just don't make as many," he said. "America's teeming with them, but we just don't do them here.
"Russell T Davies, when he reimagined Doctor Who, sort of opened the doors. I think it suddenly opened people's eyes, because it was a success and you had a whole raft of them for a while.
"It's harder again now – because you've got less channels doing it, and also young people don't watch as much television. Young people make up a significant proportion of the potential audience for this sort of show – and you're competing with Facebook, social media, the internet, Netflix... a huge diversity of channels.
"Back in the day, there were four or five channels and no internet, so you had more of a captive audience – and the shows that get huge audiences, on BBC One and things, tend to be aimed at an older audience.

"So it is hard to get those sort of shows off the ground. But I do think they travel quite well internationally when you do [get made] because mythology and horror speaks to an international audience. The same things scare us – exorcism and vampires and things are across all cultures."
Of the shows that once shared Doctor Who's Saturday evening slot - Merlin, Robin Hood, Atlantis – only the original is still standing.
"The Saturday night slot on BBC One which seems to have gone," Overman said. "I wish there was more [of these types of shows] – but then some people would say I'm biased, because it's how I make my living!
E4's Crazyhead will inevitably be compared to Misfits, says writer Howard Overman
"I'm not saying that there shouldn't be other types. But I think there's a balance [to strike] and I would say the balance at the moment... BBC Three, that was one of the avenues where you could tell these stories, with shows like Being Human, The Fades and all those sorts of shows, and that's a channel gone.
"With BBC Three all but shut down to drama – I think they're doing one drama now, the Doctor Who thing [spin-off show Class] – E4 is probably the only game in town in terms of a show like Crazyhead."
Crazyhead stars Cara Theobold and Susan Wokoma as two young women with the power to see demons hiding in plain sight amongst humanity.
The show kicks off tonight at 9pm on E4.
