A little bit of spoilers for the movie***
I think Cole Sprouse did an excellent job in the movie. He portrayed the character really well. I also liked Lisa's sister in this. She was very kind to her even though she thought Lisa was weird.
I didn't like the movie overall. I felt like the character for Lisa tried too hard to be edgy or an outcast.
I didn't like her character for him. She seemed so over the top with everything and then tried to push all the blame on him for the killings when she literally was fine with it the whole time.
The dad was horrible. He acted as if his wife dying wasn't a big deal and didn't care how his new wife spoke to his daughter. And the fact he was overprotective of the step daughter but not his own, that alone was a bad character trait.
