JSONのレスポンスを格納したい

やりたいこと

JSONのレスポンスをStructにCodableを使いまとめてTableViewにString型として表示したい。

疑問点&エラー

var movies = MovieStruct() Missing argument for parameter 'from' in call(insert 'from' <#Decoder#>)

と表示されます。元々は

var movies = [MovieStruct]()

上記のように配列に入れていたのですがAPIのRequestしたところ配列(辞書型？)にはなっておらず全て{}で返ってきていたため
上手く表示されておらずdecodeも配列で返すのを直したのですがmoviesに構造体からきたデータを格納したいのですが
記述の仕方があまりよく分からず。調べても配列で返ってきているAPIの物ばかりなので質問しました。
