No, I´m not an expert on Casanova. Therefore I did some research after watching this movie. One episode stood out from his life if you ask me. He had a child with his own daughter. I thought that Casanova only had affairs outside his family. I don´t understand or approve of that decision.
But all in all I guess that Casanova, above all, was most famous for his love affairs with many different women. And most love affairs have a great amount of romance, passion, seduction and flirtiness. But "Dernier amour"/"Casanova, Last Love" has too little of those feelings in my opinion. I understand that older people usually don´t have the same energy as younger people. But love affairs can contain many different things, not just bedroom stuff.
I didn´t regret watching this movie. It has beautiful costumes and some tender moments. But I don´t know if I would want to watch this movie again.
