Stupidity: This highly prepared organisation knows Dracula is coming, but comes armed with guns they're not prepared to use, and allow him to grab a weapon and shoot one of them. Then they give him a tablet but assign the most basic of passwords to the Wi-Fi, rather than disabling it entirely, or even just giving him a Kindle, given the only point of it was access to books. Plot-serving idiocy.
Dracula (2020)
1 stupidity in season 1
Starring: Dolly Wells, Claes Bang, Joanna Scanlan, John Heffernan
Other mistake: At the end, when the reflection of burned Lucy still shows her beautiful, Dracula's reflection shows him as he is seen; not old and ugly as in his usual mirror reflections.
