I have heard of this "Different Dimension Hacker" for a long time, the so-called "inspiration source of "Inception", after reading it, I think that it can be summed up in one sentence, this is a "de-wonderful but more story." For the slick Inception and The Matrix."
The shortcomings are mainly in the settings.
First of all, the design of the second-level world and the third-level world is too similar. The edge of the second-level world seen by Hall is almost the same as the edge of the third-level world described by the bartender, and the two virtual worlds have the same "reverse travel" bug. If we think that the two virtual worlds are programs written independently by two groups of people, then the two programs are so similar, which is very unreasonable from a probability point of view.
Secondly, the setting of "reverse travel". If this is a bug in the virtual world, then the heroine seems to have known about the existence of the bug. She called the black police detective and then used his hands to kill her husband's consciousness before the bartender reversed into the second-floor world (at this time the audience knew the existence of "reverse travel" for the first time), and she told the black police detective The sentence "What took you so long" in the 1st floor, and she didn't show any surprise to see Hall after returning to the first layer of the world, which all implied that she had known about the existence of the bug for a long time. So how did she find out about the bug, and why didn't her husband find it or detect it but didn't guard against it?
Finally, the timing of the traveler entering or exiting the virtual world is often poor, which leads to quite a bit of plot advancement. For example, Hall woke up and found bloodstains and blood-stained shirts in the house, indicating that the traveler did not try to prevent Hall from discovering these traces after killing people. Another example is Whitney's crossing, which happened to be on the way of the bartender who was kidnapped and driving, and the crossing caused great danger. From the plot of the heroine "falling in love with Hall long ago", we know that traversers can observe and understand the virtual world in the upper world, so why not observe in advance and find a better time to traverse before crossing?
In addition, standing at the time point of 2022, it may be a bit nitpicky, but I still feel that the visual presentation of the edge of the virtual world is relatively sloppy.
