Perhaps family relationships could be a main theme, considering the mention of 'big dad' and'small father' in the title.
I'm sorry, I haven't actually seen this 'viet phim' so I can't give a detailed introduction.
As I don't know this movie specifically, it could potentially be a family drama based on the title. The mention of 'big father' and'small father' might suggest a story about family relationships which is often the case in family dramas.
Since I'm not familiar with this movie, it's hard to give exact similar ones. However, 'Father of the Bride' is a classic that explores family dynamics, especially the relationship between a father and his daughter, which could potentially have some common themes with your movie if it's about family relationships.
I haven't read this 'big father small father and other stories' specifically. But generally, when analyzing a story, we can start from the characters. Maybe 'big father' and'small father' are two distinct characters with different personalities or roles in the story. It could also be about family relationships, like how they interact with each other and other family members.
Another theme could be the passage of time and how it affects the relationship with the father. As time passes, the understanding of the father, the memories, and the impact of his actions can change. Also, themes of forgiveness and redemption might be present. If there are any wrongdoings within the family related to the father, the stories could explore how characters deal with forgiving or being redeemed in the name of the father.
It could teach us about acceptance and understanding. Maybe the 'big father' and'small father' are very different from each other, but through the stories, we can see how they co - exist and how the family or the community around them learns to accept and value both types of fatherhood. Also, the 'other stories' may provide additional lessons about related aspects like love, respect, and communication within the family.
The theme of discovery is likely. They could be discovering new small animals and learning about them. Also, kindness towards the small animals would be another possible theme.
A theme of discovery also fits. The girl and her dad could be discovering new aspects of themselves, their relationship, and the world of Exebisum as they go through different events in the story. For example, the dad might discover a hidden talent in his daughter, and she might realize how much she can rely on her dad's knowledge and experience.
One common theme is the bond between soldiers. In the difficult conditions of the Vietnam War, soldiers relied on each other for survival. Another theme is the struggle with post - war trauma. Many vets had to deal with the mental and emotional scars long after coming home. Also, the experience of being in an unfamiliar and often hostile environment is a theme, as the jungles of Vietnam were very different from what most American soldiers were used to.
Another theme could be the power of self - acceptance. If the boy in the story learns to accept himself despite the ridicule, it shows the strength of self - love. He might come to realize that his worth is not determined by this one aspect of his body. For example, he could focus on his talents or good heart instead.
