Generic conventions in this misfits episode includes:
A femme fatal called Lola. She is seductive, attractive, manipulative and pretends to be vulnerable (when she head-butts the wall). Lola also dies at the end of the episode which is conventional.
There are black and white scenes, many shadows are included and the clothing is very conventional as it is in the 1940s style.
Filming in a bar is very typical for a film noir, but they are not usually as busy.
close ups and over-the-shoulder shots feature in this episode mostly when Lola is smoking.
However, this contains unconventional aspects such as:
It is British rather than American. It is modern and the everyman is black, he is in his early twenties and doing community service.
The everyman calls it a 'Zombie Noir' as there is a sic-fi element as the everyman (Curtis) becomes a zombie.
