A Christmas Carol (2022)

A Christmas Carol and Blind both feature revenge plots for abuse and focus on the troubled brotherly relationships of main characters.

Young prisoners are subjected to awful treatment at the hands of their guards and fellow inmates. Stories of juvenile delinquents behind bars.

Juveniles end up in prison and struggle against corruption and fellow prisoners for survival. Bullying and personal vendettas.

A mentally impaired person is targeted and mistreated. Institutionalized people are mistreated. Corruption/abuse of power

Both films star Park Jin Young in a role where he stands up to bullies and tries to protect someone weaker than him.

Episode 1 of “ Drama Special Series Season 3: Sirius (2013)” is similar to “A Christmas Carol” because an identical twin brother gets into trouble trying to help his younger sibling who is being bullied.

Just watch the trailer thats enough to convince you why it should be a recommendation if you liked Weak Hero Class 1.
Its a high school violence bullying revenge story

Both movies portray society's darker or tougher side. They each carry a heavy toll, but it is also remarkably well put together. Similar elements, like injustice and mistreatment of individuals who have disabilities, were present in both movies. Sadly, one is inspired by an actual story, and the other is not.

In contrast to Silenced, which centers on pursuing justice, A Christmas Carol centers on seeking revenge.

One of the things I noticed about A Christmas Carol was that it brought me the same pain and discomfort as Silenced did.

En ambas, el hermano gemelo va a vengarse de la muerte de su hermano (en Dokgo a una escuela de delincuentes y en A Christmas Carol a un reformatorio). Dokgo se enfoca más en las peleas y A Christmas Carol en las barbaridades del ser humano.

If for some reason you're looking for very dark dramas with revenge plots, I believe King of Pigs and A Christmas Carol have it. These two are similar as they deal with: hardcore bullying, s*xual assault, and other violent themes.

Aside from the aforementioned, both contain a revenge story. Whilst Kyung-min avenges his lost childhood in the King of Pigs, Il-Woo attempts to try and fight for his brother's death in A Christmas Carol.

Both have characters with mental disabilities, though they differ.

I believe these two films should have warnings of their own as they're both mentally torturing to watch, and are embedded in your head forever. I highly advise that you take precautions and only watch either one of them if you're truly mentally capable, as I had nightmares after finishing King of Pigs.

The brother is the sole caretaker for his brother. He feels miserable having him as a brother and acts in a way that will make you think he hates his brother. In the end you will soon realise he loves his brother but almost failed to show it.

Overall environment at school/youth correctional training place is filled with crooked officials.

A lot of fighting, and both protagonists seek revenge.

Endings are similar.
