I like the idea of the movie because it explores one of those "what if" questions that I've never really thought that much about. We all know about Amber Alerts and some of us have actually seen them. What if you did see a car on an Amber Alert sign? What if you knew that there was a child in danger inside that car? What would you do? It's an interesting question to ask and one that I was excited to see explored.
To be fair, this is actually pretty believable. Two people that have known each other all their lives have probably had a lot of fights and it's just the way they communicate sometimes, I get that. The dialogue isn't that bad either, and often sounds very natural as the characters fumble their lines and stutter and what not. It just really needed to be toned down in this movie to keep Sam and Nate from becoming the unnerving assholes that they become. The audience is supposed to be on their side and supporting them all the way, not wanting them to get into a head-on collision with the gray Honda just to shut them up.
I think fans of found footage should give Amber Alert a look because it has a few clever ways of making the technique work for its story. A little thing like logic doesn't play a very big role in the movie but the main idea of the story is a good one to explore. Don't let the annoying characters make you shut the movie off after 20 minutes - I still say to give Amber Alert a chance, even though most reviews tell me that a good majority of viewers will hate it.
