The group teams up with Mu’s **El** and heads into the **Bermuda Triangle** to stop it. Whether they succeed is what the film explores. You can read more about the franchise on [Wikipedia](https://en.wikipedia.org/wiki/Doraemon).

## Why This Run Matters?

Family animation tends to be strong on weekends and soft on weekdays, because school and work keep audiences at home. A modest Monday drop suggests the film is drawing steady repeat and family viewing instead of just a one-time rush.

Trade estimates also say it should keep gaining traction with similar momentum over the coming weeks and close its run on a healthy note. How far it goes from here is the interesting question. Follow our [box office updates on Technosports](https://technosports.co.in/) for the next numbers.
