It's not uncommon for actors in their 20s to play teens, but these actors are at least in their early 30s. If the story was about college aged kids they might have had a better time passing them off, but it isn't working as teens. If you can get past that major distraction, then the story is worth the watch. It's not an Oscar winner just a quality lower budget horror. Do understand that it is a horror and not so much a sci do.
