During the 1970s terrified children would hide behind the sofa in a bid to escape the Daleks.
But these days Doctor Who fans have a lot more to be frightened of than a slow moving piece of tin made from a rubbish bin. - Poor, poor Daleks.
The next episode will see the Doctor attacked by a clan of vampires wielding sharp fangs, as he visits 17th century Venice. - On tonight, at 6pm.
Too scary for children? Young fans will be cowering behind the sofa as vampires attack in the next episode of Doctor Who.
The fifth series has already seen the Doctor face the Weeping Angels, the terrifying Smilers, and the old favourites the Daleks.
The show's new writer Steven Moffat has made it clear that he aims to scare, with some 'spine chilling' scenes. - I think we got the hint when 'The Beast Below' aired. I'm not complaining... It was a proper scare!
'We're now going for proper scares in four and five, so some good spine chilling stuff on its way,' he said.
'If you took a vote amongst the playgrounds of Britain they'd all be saying 'make it scary, you're meant to be behind that sofa!' - He's right! I honestly do not care if they make it scarier or lighter... I just want it to be DW. But, I guess, and if it's my last chance to say it... Rose, erm... Nevermind. What I mean is, I like scary episodes.
But as the aliens get ever more inventive, parents are sure to question whether their children can handle the excitement.
One wrote on the MailOnline: 'I caught the last few minutes of it on Saturday and commented that it probably would have scared the living daylights out of me if I had seen that aged around 9 or 10.
'Nowadays I think kids must be becoming de-sensitised.'
Another viewer loved the thrill.
'I was hiding behind the cushions and occasionally watching through the crack of the living room door in the 1970's and I loved every chilling minute of it!
'It was just as scary then as it is now.'
Patrick, from Slough, commented: 'Wrong wrong wrong.. Basic rule has always been - 'No sex in the TARDIS'
'The Doctor's essential 'otherness' is destroyed if he gets sexually involved with his companions.'
And Soaks from Sevenoaks wrote: 'Many children look up to Dr Who so what message are you sending out to young girls and boys? Why not change the record and bring in intelligent, classy women?' - Doctor Who is evolving, and unlike before... I have no opinion on this. I enjoy DW even when the episodes are a bit more sassy. Or the assistant, for that matter. It has always been there, I guess. But I like them both ways. But I agree with the 'no sex in the TARDIS' rule. I don't mind some hints (Captain Jack being a good example of it, although I often felt it was too much), but that is about it. So, no, I wasn't 'affected' by last week's episode.
This week's upcoming episode, written by Toby Whithouse, sees the Doctor, played by Matt Smith, taking Amy for a romantic mini-break in Venice.
But when the Tardis lands in the city, they discover dessicated corpses and terror in the canal.
They need to get past the blood-sucking residents of the House of Calvierri and the rest of the scary vampire killers.
