Definitely for kids. Adults will soon notice that the actress who plays Harper is usually expressionless, and very seldom smiles, laughs or shows any degree of emotion. Griffin does better, but for a kid, he is way too practiced at controlling his emotions. Topher, Savannah and Griffin’s younger siblings are much better at actually behaving like kids.
The parents are useless; they blunder around, barely noticing what’s going on around them. The basement of Tremont House has a bomb shelter added on, complete with all lights working and apparently switched on all the time, yet no one notices the electrical usage or wonders what’s drawing that power. All Griffin’s parents do is tell the kids to stay out of the basement, too afraid to investigate anything. Harper’s mom keeps going on about a scary curse on Tremont house, and has no curiosity at all about what Harper and Griffin are finding out. Any parent worthy of the name should be right out there with them, helping to solve the mystery, not just telling them to do their homework, make dinner or go to bed. But in order for this show to work, adults have to take a back seat to the kids.
Kids will certainly enjoy this show, with its intricate plotting and interesting adventures, but adults will probably prefer something their own speed.
