LET’S SEE IF WE CAN FIGURE OUT WHAT HAPPENED TO OUR PHONES: When all of their cell phones went crazy and “barfed” simultaneously, Tuck (Astro, right), Munch (Reese Hartwig, center), and Alex (Teo Halm) decide to find the cause of the disturbance. Their quest leads them to a remote site in the Nevada desert where they find Echo, an alien from another planet, who desperately wants to go back home.

Most people know that E.T. is about several kids who befriend an alien that has been stranded on Earth and who is eager to return home before suspicious adults can do him any harm. That classic film won four Academy Awards in 1983, and was even voted the best science fiction movie of all time in a recent survey by the web site Rotten Tomatoes.

However, if you’re too young to remember Steven Spielberg’s heartwarming adventure — or if it’s been so long since you saw it that the story is a little fuzzy — have I got a movie for you. Much about Earth to Echo screams remake, starting with the picture’s vaguely familiar poster that features a human hand reaching out to touch an extra-terrestrial.

Still, this remake refreshes the original by incorporating current cultural changes such as texting shorthand and the use of social media. So, when the protagonists communicate with each other, they often rely on inscrutable slang that may befuddle folks who are unfamiliar with the slang employed by today’s average adolescent.

As the film opens, we find the narrator Tuck (Astro) lamenting the impending separation from his BFFs Alex (Teo Halm) and Munch (Reese Hartwig) because their Nevada neighborhood will be razed in a week to make way for a turnpike. The plot thickens when all their cell phones inexplicably “barf” simultaneously, and they decide to try to find the source of the mysterious malfunction.

Equipped with a camcorder and state-of-the-art spyglasses, the youngsters ride their bikes into the desert in the middle of the night, accompanied by a rebel (Ella Wahlestedt) who is running away from home. Their GPS device sends them to a site in the desert where they find Echo, a cuddly visitor from another galaxy who, like E.T., is anxious to return home

The kids, of course, go into high gear to help Echo, keeping just a step ahead of the untrustworthy authorities. Their efforts lead to a satisfying resolution every bit as syrupy as Spielberg’s in E.T.

Excellent (****). Rated PG for action, peril, and mild epithets. Running time: 92 minutes. Distributor: Relativity Media.
