Look, this is a 2015 Nickelodeon-style TV movie that nobody asked for and even fewer people remember. The ratings tell the story: 5.7 on IMDb, 2.3 on Letterboxd, 58% audience score on Rotten Tomatoes. It's not offensive, it's not scary, it's just... there.
The premise—ordinary kid accidentally becomes popular when everyone thinks he's a vampire—could've been fun in more capable hands, but this is bargain-bin entertainment. Your kid won't be traumatized, but they also won't remember it by next week.
If your 8-year-old is begging for a vampire movie and you've exhausted Hotel Transylvania, fine, put this on. But there are dozens of better options that are just as safe and actually, you know, good. This gets a low WISE score not because it's harmful, but because life's too short for mediocre content when great stuff exists.
