It's not brought up as much as even True Romance or Natural Born Killers (which he took his name off of) b/c it's seen as a blemish on his resume. Even though it was the intention to have an ongoing plot get thrown into chaos by running into a bar of vampires, the A-Story was too damn good and everyone wanted to see that play out rather than a vampire killing gore fest. Them meeting their connect and Richie's psychotic obsession with the daughter fukking something up in what would be a otherwise smooth parting of ways and how that plays out is so much more interesting than what we got.
That said, I still appreciate the flick for what it is, but the beginning was too damn good to abandon.
