Why are there 2 classes that are exactly the same about movienight HOT 1 OPEN

You're going to kick yourself when you see this https://github.com/mrsegev/MovieNight/blob/089768c55cb26281a08812f3d65e315fa26b2422/data/src/main/kotlin/com/yossisegev/data/repositories/MoviesRepositoryImpl.kt

Essentially the repository delegates to the datastore in a factory-ish way. Whilst it's not imperative they share the same signatures, it probably made writing by one person easier.

In a team environment, this is less likely to happen. Also if you reduced to a single signature, you'd never know if people were binding to the data store directly (what the repository is designed to stop happening so you can switch stores / store implementations).

There is a great write-up, which is how I got here, which seems to cover this https://proandroiddev.com/a-guided-tour-inside-a-clean-architecture-code-base-48bb5cc9fc97
