What about subtitles?

With or without subtitles?
Do not be afraid that when watching the series you will not understand some words or expressions. That's what subtitles are for. Here are the three most common options:
Only Russian subtitles
English subtitles only
English and Russian subtitles
Which one to choose when viewing is up to you. Most online players offer both double subtitles and separate ones. Russian Russian and English subtitles are usually chosen by people to learn the language, so that they can not only perceive speech by ear, but also see how words are written and how this or that phrase is translated into Russian.
Russian Russian TV series with Russian subtitles are preferred by those who want to watch a new series without waiting for a translation into Russian, and are not very interested in a detailed analysis of the new vocabulary.
If you decide to watch the series only with English subtitles, then you probably already know the language well and have a rich vocabulary, and you may need subtitles only to understand the rapid speech of the characters, see how certain words are written or correctly translate a phrase yourself.
Learning English on TV series with subtitles is recommended for both beginners and everyone else. It is important to choose the right series that corresponds to your level of language proficiency and approach the process correctly.
