Within the first few minutes of the movie I was thinking about The Goonies, a movie I love and still watch regularly. The basis for Earth to Echo is that a group of three best friends (Tuck, Alex, and Munch) are going to be separated because there is a freeway being put right through their neighborhood. Just like The Goonies were going to be moving due to a golf course being built. And at some point during the movie a girl is added into the mix, just like the two girls show up in The Goonies movie.
The way the movie is done is as if the characters, themselves, are recording the whole thing. So we, the audience, are seeing what the boys are seeing. It's a pretty cool point of view to have while watching a movie.
My son loved it and wants to see it again, already. My daughter held onto my arm the whole movie and was a little scared when they first found Echo (whom she says reminds her of a dog) but she sat through the whole movie, which she wouldn't have done if she didn't like it-trust me.
It's a great summer movie for kids. There is a point that there is texting back and forth between the boys, so for early readers you will have to read the texts for them. It's rated PG for some action, peril, and mild language.
