Is Day One Worth Watching?
Just like other tech thrillers, Day One centers on a dangerous technological discovery that threatens to change the world.
The series follows Ulises as he returns to the tech world after the death of an old friend, trying to track down the murderer while uncovering a corrupt tech company engaged in unethical practices, including killing people in the name of “innovation.”
While the story leans on familiar clichés, the series does a good job of keeping viewers engaged, especially by highlighting the threats posed by AI and the erosion of privacy and personal freedom.
However, despite its focus on technology, the show lacks a clever twist that will truly shock viewers by the finale. Nevertheless, it’s still an entertaining watch, and audiences may enjoy seeing why Ulises decides to return to his profession after a decade-long hiatus.
