Many people watch this series of movies and wonder if it is a parallel universe, and how it affects it. In theory, it will not work. I think thinking about these questions goes against the original intention of the director and screenwriter. Of course, maybe the third director wants to make a horror movie. It can also be seen from the encyclopedic explanation of the movie title. What he wants to let people know is that if you can go back in time and change things, the result is not necessarily the result you want.
Most people regret some things, saying that if it was like then, it will not be like this now. The Butterfly Effect movie is to tell us that even if you go back to the past and didn’t do that at the time, you will be affected by other little details. It's still unsatisfactory after so many years.
But the 3 shots were too bloody and violent. It's not very good to let 2 people wear it at the same time.
