would u let your children to watch horror movies?

Mmhmm. Any age is fine with me.

yes when there 10 或者 11 o_o

My son is 2 years of age at the moment and even now i allow him to watch the 更多 'suitable' horror movies, ones with a minimum of bad language and the minimum of actual scary-ness. Blood, guts, gore is fine. Children 爱情 that kind of thing.
From the age of 12-15, he may watch whatever he wants to watch but there will be ground rules. If it is a movie of 18 i will watch it first to see if it's appropriate and he does not act anything from the movie, repeat anything of a bad language from the movie unless quoting and only then! And he also promises never to lend to a friend 或者 watch at a 老友记 house without 说 老友记 parents permission. His 老友记 will also not be allowed to watch 电影院 above their age at our house unless the parents permission has been 给 to me and me only.
From 15 years of age, he can watch anything he so wishes and i won't bat an eyelid. From 15 i think he'll be mature enough to understand etc. So it's his choice and his responsibility.
