Olá, Mundo

You must watch the 3 episodes before the movie to understand what's happened and why . The first half was good but the problem is that they tried to show alot of things related to quantum physics, and the last quarter was too complicated and not very stable. Nice movie but not great one.

POSITIVE: The animation looks stunning, the art style is pretty unique for an anime. The characters are cute especially the main 2 character. The movie reminds me of Doctor strange which is good and cool.

NEGATIVE: The plot is messy its just the writers are doing too much to the plot and its messy in my opinion (I fully understand the movie so everyone who reads this can't blame me for rating this movie on average score)

Since the movie is all about complex programming and its manipulation, its title alludes to the "Hello World" program which is often used to represent the basic syntax of a programming language.

The story involved at least 3 up to n worlds (real & virtual). It was a bit confusing while watching, but took hours to digest and analyse the storyline. The deeper you analysed, you will figure out how complicated the whole story was!

ps Tenet is too easy compare to this.

As a Sci-Fi lover, Hello World was an unexpectedly great experience for me. As it goes for most recent anime films, the visuals are fantastic and spice up the experience the film delivers. Although, as few as they are, the characters are not deep and certainly needed more development. The way the plot is explained is also not very clear and may leave the audience baffled. These two points are probably why it is rated as it is, since probably most people didn't really understand what was going on.

But Sci-Fi-wise, the story is quite brilliant. At first it starts like a run-of-the-mill high school romance drama, but soon enough it changes with the appearance of the future Katagaki. And as the film gets into the second half, with some quick hints here and there we realize the story is more complex than what we thought it was. Saying anything further, borders on spoiling the story, so if you like Sci-Fi stories, give this one a try and enjoy.
