I don't understand people saying the girls were annoying. I think that's probably how a kid would act in that situation. If you want to see annoying watch Babadook... that's annoying.
If you can get through the entire movie you're doing great. Looks like it was filmed in an old barn or warehouse.. terrible. Acting was not that great.
I just watched an episode all these years later. I must have chosen not to watch when on network due to the cheap looking special effects and using old airwolf footage.
