First of all, start the conversation with a question that interests your interlocutor, for example, what genre of movies and TV series he likes. This will help establish initial contact and understand the preferences of your interlocutor, which is a good start for an interesting conversation.

Remember that you should not immediately share spoilers or express categorical opinions. Some people can be very sensitive to the disclosure of key plot points, so it is important to clarify whether your interlocutor has watched a particular movie or TV series before starting the discussion.

Pay attention to the reaction of the interlocutor. If you see that the person is not showing much enthusiasm, it may be worth changing the topic or returning to the questions to include them in the conversation again.

Try to keep the conversation mutual. Share your impressions, but also give the interlocutor the opportunity to express their thoughts and feelings. This will create a dynamic conversation and show that you are truly interested in their opinion.

Finally, do not forget to maintain a positive attitude and openness in the conversation. Even if your views on films and TV shows differ, respectful attitude to other people's opinions will help to create a friendly atmosphere and make the conversation truly enjoyable.
