There are a lot of actors in Stranger Things but my favorite has to be Millie Bobby Brown who plays Eleven. There are a lot of people who say that her storyline in season 2 is not really the best but I believe that it only managed to show her acting prowess more. Her character was able to show a lot of realizations that can make people connect with her properly.
I think it is also cool that she gets nosebleeds all the time. The various characters are all changing their mindsets and they are also showing that they are maturing every day. Eleven is one of the main characters that you need to watch in the long run.
