Retrofit 2 возвращает Null

Первый раз использую Retrofit, прочитал принцип работы, попробовал реализовать, но в итоге возвращается null. Искал на русскоязычных и на англоязычных сайтах, но ни один из способов мне не помог. Подскажите что тут не так.

Ресурс с которого нужно получить инфу: https://s3-eu-west-1.amazonaws.com/sequeniatesttask/films.json
