Is it eulogizing or sarcastic?

Just after watching this movie, I feel that the story is relatively old-fashioned, like Resident Evil, 28 days later, 28 months later, it is the story triggered by the "virus" created by the innocent and kind human beings, but the protagonist has been replaced by the prestige. Smith, the story takes place in New York, the story focuses more on describing the "legend" who thinks he is the last person on earth to live alone in this world.
In fact, after I personally watched this movie, what I care more about is whether the movie eulogizes or satirizes the real world we live in?
Three years after the virus outbreak, only Will Smith is left in New York City. At first glance, the empty New York is in dilapidated conditions and the weeds are reborn. But think about a world with only zombies. Why is this New York metropolis in three years? Didn't turn into a garbage dump? In this seemingly depressed city, there are all kinds of birds, there are reindeer, there are lions... They live together in harmony and obey the laws of nature; the sky in New York is so blue, and the flowers and trees also show With vigorous vitality; the zombies living at night have their own strict social organization, have extraordinary wisdom, and have a strong body beyond human beings. More importantly, they have not killed each other like we do now, and have not killed us. The same is constantly destroying nature and destroying the natural environment on which we live, but trying to do it. In the city of New York, "zombies" and nature, as well as all kinds of things in nature, are the same as them. The harmony and coexistence of animals with the right to live, from a certain point of view, are they not more intelligent and advanced than us?
Nowadays, we always report how much progress we have made in overcoming human diseases, but have we ever paid attention to that we have destroyed the last virgin land on the earth-the fund of mankind, we may be able to benefit mankind through genetic modification , But will they mutate themselves again as described in the movie? At least in the real world, in 2003, the civet cat virion became the SARS virus that threatened humans or the Chinese people the most. Then we still have to allow our "scientists" to continue to engage in research on human genes and cloning?
It’s hard to tell which question is right or wrong, but we can learn from the past...

Is this film eulogizing or satirizing, depicting the future or vigilant against reality?
