That's awesome you have something you like which you can enjoy together with your daughter. I think the age restriction is flawed, but is set up as a precaution to protect the children. Smallsteps might be advanced for her age mental wise, but some kids might be behind. That is the reason for the blanket age like that. I compare it to like the school system where there are grades, but the level of intelligence of students can vary greatly within it.
I think horror was mostly the movie I was too young to see. There were a lot "Shake Rattle and Roll" films during Halloween season, and they just show it on TV. I think they were rated R13, and I was watching them when I was 7. There were a lot of scared moments after watching it, but is now a fun memory I have with my siblings.
