The Strauses used their tech savvy to make a marvel of logistics that looks every bit as slick as a studio tentpole. It's just a shame they haven't figured out a way to CG a decent story. Yet.
Trapped inside what looks like a Marina del Rey condo complex, the principals raise and lower the blinds, run up and down the stairs and occasionally venture outside, while the audience, if it has the energy, yells: "No! Don't do that! That's stupid!"
More and more frequent attacks by the brain-sucking outer space invaders... don't come so much as frights or thrills as they do a form of relief; as long as the mayhem's going on, we're spared the dialogue.
