The interesting thing about the film is that it combines "Fight Club" and "First Fear", playing a trick of split personality and disguise of disguise, giving the audience a great shock in the last fifteen minutes, and the ending is reversed and reversed. The director It really hacked the audience, and once again pointed out that people cannot always hide behind his computer. The biggest security hole is not in any program or server. Humans are the biggest security hole.
Although the film has two classic films for reference, the integration of the plot still has its own characteristics, and to some extent it has also compromised the audience's bridge reserve system, which is why it is popular.
The cost of this independent production is not high. It portrays the hacker world as another martial arts world. It also uses reality and virtuality to distinguish the two-dimensional world of hackers in reality and the network. Hackers use network systems with increasingly higher levels of protection. To distinguish the status of the rivers and lakes, but the most challenging system is the human mind, and there is no security system that is more difficult than the human mind .
