Matt is the responsible, painfully nice brother, while Deco is not. The sunlight is really bothering him this morning, so he begs Matt to let him into their mum’s house. She threw him out because of his stealing ways, but Deco can still exploit his brother’s guilt. Awkwardly, he repays Matt’s mercy by projectile vomiting blood in his face. That won’t be the last time that happens in this movie.
Soon, Henry the vampire slayer is on their doorstep, pretending he is there to help. Slaying is personal to him, because the leader of the pack is his beloved fiancée, who was turned during her bachelorette party (in Romania, because it was cheap). He keeps tabs on vampire movements through reports from his fellow cabbies (which is kind of clever).
Wrong One is often funny, but almost always in an outrageous meatheaded kind of way. The story itself is no great shakes, whereas the best horror-comedies (like Extra Ordinary) have a narrative that would be interesting even without the laughs. Despite the intentional echoes of the title, Wrong One never specifically spoofs Let the Right One In. They both just happen to be about vampires.
