The only benefit to these holidays is to create fun memories for kids and for hobbyists to make decorations to sell and inspire them.

I don't think we should do away with Halloween, but we should definitely do an audit of exactly what it's teaching our kids through the symbolisms and customs. Toss the crap commercialism, and bring it back to a seasonal reprieve from the realization that every year we have to prepare for a dismal few months of cold, wet, and brown/gray.

Aside from that, the subject matter doesn't matter too much. We can easily put a fresh coat of paint on the holiday without having to scrap the whole thing. The same can be said for every holiday, as well.
