The proposed application has several modules that interact with each other. The interconnections between these modules are as follows:

1. The CLI module interacts with the MediaManager module to receive user commands and provide output to the user.

2. The MediaManager module interacts with the MetadataUpdater module to update metadata for media files.

3. The MetadataUpdater module interacts with the MetadataProvider modules (i.e., IMDbProvider and TheTVDBProvider) to retrieve metadata for media files.

4. The MediaManager module interacts with the MediaFile modules (i.e., Movie and Series) to perform actions such as renaming and updating metadata.

5. The Movie and Series modules inherit from the MediaFile module to share common functionality.

6. The MetadataProvider and MetadataUpdater modules use HTTP requests to interact with external APIs, such as the IMDb and TheTVDB APIs.

7. The IMDbProvider and TheTVDBProvider modules use API keys to authenticate requests and retrieve metadata from their respective sources.

8. The MediaManager module interacts with the file system using the os and shutil modules to scan directories, rename files, and move files to new directories.

Overall, the modules are interconnected through method calls and parameter passing, and each module has a specific responsibility and interacts with other modules to accomplish the overall goal of renaming and updating metadata for media files. The use of modules and object-oriented programming allows for modularity and extensibility of the application.
