I think that Katherine McNamara is not suitable as the leading actress because in the series she shows bad acting skills. Maybe because she's young and she needs to experience more. Her acting gets me like "what? is that how she should do the acting?" and it's kinda irritating. The supporting actors and actresses lift her and I think if they are not good supporting actors and actresses this tv series will not be as good as the movie. They should have picked a capable actress that can show real emotions unlike Katherine McNamara. I have to be honest that she has bad acting skills and what I notice the most is seems very flirty whenever she is acting and when she's angry she's out of character. Her delivery of lines as well and her tone, it is all lacking. But the story itself is really amazing and full of surprises. The main lead just really bothers me the most.
