"Don't be greedy" sums up the depth of this movie. All the rest of the baloney is big budget window dressing. The movie rotates through hiding the ball annoyingly and revealing too much. None of the potentially interesting plot tangents are developed yet the trite ones are hashed and rehashed to excess.
The charm of DD, as others have pointed out, was in the schizophrenia device,the humor woven into the fabric of the movie, and most importantly, the acting. There is enough wooden acting in The Box to attract a giant mound of martian termites.
The biggest problem with suspending disbelief during this mess is the glaring question, "why would a technologically superior power capable of taking over the government need to do any testing at all?" Awful failure of a movie.
