If considered purely as a straightforward love letter to the vampire genre, and an expression of affection for the clichés and tropes these movies use over and over, Night Teeth can be a good time.

Nothing special, but it is fun.

[Fry's] increasingly unhinged performance ensures that "Night Teeth" isn't an entirely bloodless flop, but even she stalls out as the film crawls along beyond a 100-minute running time.

Night Teeth could have been a pretty decent vampire/gangster mashup, but the convoluted nature of the world and the lackluster love plot sink it faster than a vamp can sink its teeth into a willing neck.
