映画「複製された男」

自宅、字幕。
意味不明。普通自分と完全にそっくりな人間を見つけたら、気持ちは上がるだろう。ＤＮＡを調べるとか、出生の謎を探るとか、あるでしょう？シュールな映画なんだろうけど、登場人物達の行動が理解できないせいで、疑問で頭が一杯になる。

It didn't make sense at all. Normally, if you find a man who is entirely similar to yourself, your feelings would rise. You would investigate DNA, or would try to solve the mystery of his birth, or would do something. Am I right? Even though it would be a surrealist film, I couldn't understand the behavior of the characters, therefore my head filled with questions.
