One of Hypercube's screenwriters, Ernie Barbarash, took over directing for the prequel to the original Cube film, which is why I'm so surprised that it's actually good. Barbarash must have had his input universally shut down for the script to Hypercube, because Cube Zero is superior in every conceivable way. Hypercube failed at linking the suspense to the origins of the cube, but Cube Zero decided to start on the outside and work there way in, exploring the reasons behind and purpose of the Cube... One of the things that make the original Cube so fantastic was the lack of explanation of these things, but with the third installment of a franchise, new ground has to be explored, which Cube Zero successfully did. They even managed to link the ending of the film with the beginning of the original one in a way that both makes sense and benefits both films. The acting and dialogue was significantly better than the second film and on par with the first. Bottom line, this is a very good sci-fi B-movie, especially for a prequel. This might actually be the best prequel of it's kind in existence. I mean, it's not a good movie by any stretch of the imagination, and the escape scene is horribly done, but it's great for being what it is. I'd recommend it to any sci-fi/horror fan... The ending flows so naturally, that it might even be better if you watch Cube Zero before the first one (which is a better movie overall)... I'd pass on Hypercube (unless you're in love with the other two).
