@riviraadrian

const filteredList = watchList
.map(film => ({title: film.Title,rating: film.imdbRating}))
.filter(film => Number(film.rating) >= 8)

If I test only these lines, then the challenge passes for me. Make sure you have made no other changes!

(Side note - usually you want to put filter before map)
