I have to say that neither the second nor the third 0 surpassed the first cube.
I think the first cube is to use the shell of science fiction to express some philosophical things, some problems of human society and so on. And the second hypercube is to use the shell of science fiction to express a conspiracy. Perhaps the director has not figured out this conspiracy, making the whole story obscure and difficult to understand. Therefore, the third part did not continue the story of the second part at all, but told a prequel.
Thinking spaces, parallel worlds, hypercubes, etc., these are all over the eyes of the film, or a gorgeous rhetorical sentence in an article, and the main line is indeed that someone has entered the terrifying hypercube with secrets, and the mysterious military organization is in order to get it. Secret, sent someone in. And the others other than these two people are just a mysterious military organization to kill all those who are related to hypercube (a sad private detective, just may investigate this secret in the future, so it was also thrown in.). When the undercover agent who was sent out got the secret back (the black necklace that was finally removed from someone's neck), he obviously knew he would be silenced.
Perhaps the only inheritance that the second part has achieved is the continuation of a phenomenon: people often return to the original wildness and abandon all morals and values when there is no restraint. (In the state of killing without punishment, people are just simple food? Vent tools?)
Personally, I still think the first part is more intriguing, probably because of the difference in directors, many things have not had the opportunity to deepen in the second part, which is a pity .
