As I said, though, this could've worked out. A couple years back there was this movie called Super 8 that did work out. I've gained a reputation as one who hates Super 8, but I really don't. I don't like ending of the movie for various reasons, but the rest was enjoyable. It was about a group of kids on an adventure just like The Goonies. First off, Super 8 worked because it was Steven Spielberg himself that helped work on it. But also, it was an homage to the 80's movies that it emulated and not a complete rip-off. It felt fresh and original. Earth to Echo was done by a no-name director and written by no-name writers and it didn't seem like they had any idea of what they were actually doing and as you are watching, you aren't praising it because it's an homage and you don't feel like it's refreshing. Instead, you are just wondering what in the heck they are doing.
Overall, I suppose that since I am no longer in the 8-12 year old range, I can't be the best judge of this movie for that age range. Perhaps they will like it. But I just get this feeling that they would find this movie boring. And it's certainly not a movie I would recommend for the smaller kids. If you're looking for a movie to take your kids to, take them to How to Train Your Dragon 2 instead if you haven't already. If you've already seen that, then find a DVD to rent for them. Earth to Echo isn't worth your time. It tries to be the next E.T. or the next Goonies, but it fails. My grade for it is a 6/10.
