I wouldn't say it is all about candy and costuming of little ones. Many pagans celebrate Samhain, aka Halloween. And not as a Satanic worship I would add just to avoid that being inferred being they are pagan.My view is that today's holiday as it's celebrated has little meaningful connection to the past. I don't have any problem trick or treating, watching scary movies, giving out candy, etc. But I have little motivation to do them since I never did growing up and I still live with my family who still is against it. It's a nice excuse to wear my anime cosplay and maybe visit community events.
