Sex and the city

I've started to watch this series to train in listening (perhaps "to develop my listening skills" would be better). There are some things I like about it. I like the way main heroins heroines look. Also it's good that they are good friends and always help each other. But the way they treat men is really strange for me. More traditional relationships appeal to me more. Maybe I'm a bit old-fashioned??) Don't know what to add actually)

This is fine.  "Heroin" is a narcotic so you need to be careful with the spelling :)  "Heroine" is a little more appropriate for a novel or an old film than for a modern TV series.  Instead, you could write "leading actors" or "actors" (or just "leads" if your audience knows something about film and TV). In modern English, the word Actor is used for men and for women.
