/**
 * Instructions:
 *
 * 1. Swap `parseEventV1()` to `parseEventV2()`
 * 2. Resolve any type errors (check w/ `npm run --silent typecheck`)
 * 3. Remove any manual casts (`as ...`)
 * 4. Resolve any runtime errors (run code w/ `npm run --silent part-1`)
 * 5. Add a new handler branch for the `movie.completed` event. It should print the user's rating and the movie's title. Bear in mind that some data is on the event itself while other data is on the related object.
