Woman named Becky is killed at the very start after being tricked by Frank, and bitten by a vampire hiding in her shop. Minor incident, but still want to mention it just incase.
There is audio gore in the form of blood sucking noises in a scene at the very start, then in 2 other scenes later on. The audio is not super loud and is kept relatively short, more as way to depict the death without showing visual gore.
The scene at the start happens very quickly, so beware, but the other scenes are less surprising and you should have time to mute or lower the sound.
"Crazy" but it's used in a literal sense, people telling Miguel and the others that they are crazy for believing in vampires. Also "Buggin'" to mean acting weird.
