Xtro is an ugly, mean-spirited and despairing thriller that left me thoroughly depressed. Why was this movie made? What vision filled the filmmakers with a desire to share this work with an audience?

... Turns a space visit into a nightmare about monstrous paternity, the abuse or traumatic reproduction, into a sum of totally insane and unpredictable dream paths where the only common thread seems to be flesh degradation. [Full review in Spanish]

Xtro's potential was enormous but as it stands it is brilliant in one area only and that is its consistent mediocrity - and that's a shame.

A visual mess of sci-fi/horror clichés.
