Who still likes and celebrates Halloween?

Halloween is almost here!!!! :)
I like asking people what they would like to dress up as on Halloween and some even say that they are not gonna celebrate or go trick- or- treating! I’m definitely going to celebrate but I’m just wondering why people are just giving up on it.There’s nothing wrong with candy or dressing up or even scaring people!
Why do you guys like Halloween? Why do you hate it?
