My sister and I have just started watching a new series on TV. The first episode was gripping enough to keep my attention, and I didn't want to stop watching it. However, there are some parts that are too scary in my opinion. My sister thinks it makes the show exciting, but I feel it's not good for younger viewers. We both agree that the characters are well-developed, and the plot is interesting enough to keep us coming back. I hope the next episodes will not be too frightening!
