What did You Think of Series 10 Episode 4 Knock knock ?

Now that the fourth episode of series 10 has been aired what did you think? Was it everything you had hoped for or not what you expected.

Bill is moving in with some friends and they’ve found the perfect house – so what if it’s strangely cheap to rent, and the landlord is a little creepy?

The wind blows, the floorboards creak, and the Doctor thinks something is very wrong. What lurks in the strange tower at the heart of the building – and why can’t they find any way to enter it?

The Doctor is played by Peter Capaldi, Bill by Pearl Mackie and Nardole by Matt Lucas. David Suchet guest stars at the Landlord.

    Really liked this episode! I especially loved the guy being frozen in mid-consumption by the wall, with his blank, twitchy eyes- Beautifully creepy bit of imagery!
    Definitely think it’s Missy in the vault. I feel like in the next episode, the Doctor will find no one in the vault as Missy has somehow already escaped, so then he’ll find her a couple of episodes later, as I don’t think they’ll reveal what’s in the vault next week, and I think we know missy will appear in an episode in a couple of weeks. But I don’t know! (just a silly little theory)!

    Is it just me who really didn’t like that episode, the cast were weak and it was so over hyped it didn’t live up to expectations at all, I was at least expecting it to be creepy, I think for me that’s probably my least favourite so far

    I really hope the master isn’t in the vault, simply because it seems too obvious! I would love to be really shocked when they reveal who’s inside! In DWMthey said it would shock us, hope they’re right!

    Suchet was magical. Script was fun, cast was decent. I didn’t really get the last third but that’s probably because my dad came in loudly with some fish and chips. Wood woman looked excellent but was underused I thought and the alien woodlice I didn’t see the point of at all.

    Overall, probably a 7/10 for me, but Suchet bangs it up to at least a 8 because he does.
    The Pilot: 9
    Smile: 8
    Thin Ice: 9
    Knock Knock: 8

    Series 10 is off to a flyer – this and series 9 are the best I’ve seen this show in a long long time. Certainly best since the reboot in my opinion

    The Pilot 6/10 ok episode nothing special

    Smile 7/10 Lot better than I excepted, but still not that great.

    Thin Ice 6/10 Just watchable. Didn’t really enjoyable.

    Knock Knock 8/10 Pretty good episode. Best one of the season so far.

    I thought it was ok nothing special but still watchable, maybe Murray gold in the Vault! I reckon it’s his daughter.

  • Jordan Scott

    May 6th, 2017 - 8:36pm

    So far:
    The Pilot: 8/10
    Smile: 6/10
    Thin Ice: 6/10
    Knock Knock: 7/10

    Since I’m that used to not being surprised in Doctor Who, I’m sticking with saying that the Master is in the vault due to the way the doctor talks to him like a brother or friend.

    I think to obvious to be master as it’s moffats last series probably river song.

    ‘Knock Knock’ was a great story and gripping throughout. David Suchet stole the show as the Landlord. Certainly shaping up to be Capaldi’s best series. But what is in the vault? The fact it was playing the piano and the Doctor opened the vault makes it more tantalising.

    A decent episode let down by a rushed ending. The use of the reset button again is becoming annoying. Suchet excellent.

  • The Temporal Jelly Baby

    May 6th, 2017 - 8:24pm

    As do I!
    Revised score for Knock Knock: 7/10.
    I decided to move it down 0.5 after realising plot flaws.

  • The Temporal Jelly Baby

    May 6th, 2017 - 8:23pm

    Indeed. Though interestingly, the next episode is the 1st one with Nardole in the actual adventure – so who’s guarding the vault? There’s got to be a reason for his change in attitude there. Maybe it’s not a 3-part story coming up but almost a 4 part story…

    May 6th, 2017 - 8:22pm

    It’s probably Sherlock Holmes in the vault?!?!?!

    May 6th, 2017 - 8:21pm

    They say we will find out in episode 6 who or what is behind the door.

  • therealwhovian63

    May 6th, 2017 - 8:18pm

    Why would he want to know a story about bad things

  • therealwhovian63

    May 6th, 2017 - 8:17pm

    Exactly and if he goes against it somthing happens that affects someone. He trys to make it as commfortable for them in return

    Agreed, David was really good as the Landlord and I really hope my next landlord and student accommodation isn’t like that 😉

  • Mark Belsom

    May 6th, 2017 - 8:15pm

    Think it’s to obvious to be the Master behind the doors,I still reckon it’s another doctor.

  • The Temporal Jelly Baby

    May 6th, 2017 - 8:15pm

    Another good episode in what has so far been a good series! And David Suchet was of course great as the landlord. So far in series 10…

    The Pilot: 8/10
    Smile: 6/10
    Thin Ice: 8/10
    Knock Knock: 7.5/10

    This episode should be called:

    “Impossible try not to cringe challenge May 2017”

    I’m going to go watch Pyramids of Mars…

  • The Temporal Jelly Baby

    May 6th, 2017 - 8:12pm

    Oh, but it wasn’t the Doctor, was it? He made an oath…

  • Run you clever boy

    May 6th, 2017 - 8:12pm

    100% the Master/Missy in there probably both because who else likes stories about people getting eaten by bugs

  • prototype dalek

    May 6th, 2017 - 8:12pm

    Dark, makes a nice change as well. Got to be the Master In their

  • The Temporal Jelly Baby

    May 6th, 2017 - 8:12pm

    Interesting theory, but why would the Doctor lock them in a vault?

  • therealwhovian63

    May 6th, 2017 - 8:10pm

    I too believe the master might be in their but i thought they might be less friendly too eachother

  • therealwhovian63

    May 6th, 2017 - 8:09pm

    I dont know about that. Why does he have a piano

  • therealwhovian63

    May 6th, 2017 - 8:09pm

    Well it doesnt rule out the master from being in the vault but does make it unlikely. I think its either missy, susan or someone the doctor loves, trusts or cares for

    Definitley the Master in that Vault!!
