@britesparks: Your display is amazing and I've loved seeing outdoor displays in my area, large and small. If you want to, go for it - or at least start planning for next year so you can grab some things cheap after the holidays 
@XpressoMartini Catholics don't celebrate evil
Catholics are literally the ones who made it a worldwide celebration well before the US started exporting media - and Hallowe'en isn't to celebrate evil - the hallowed part is a bit of a hint.
The Catholic concepts prosthelytized mixed and fused with local customs and beliefs. In many European areas, that fusion made Hallowe'en. In Meso- and South America, it made the Days of the Dead where every year there is a bit of contention with some Catholic groups warning people away from Saint Muerte and others embracing it as the traditions of welcoming and remembering the dead live on. As a mix of both, I do both though lean more heavily on the latter.
It's evolved over time as each group and generation add and discard traditions. Even modern corporate additions doesn't make it inherently evil, it's what people bring to it. Some may bring vigils for those dead while dressed as skeleton, contemplating mortality while passing out candy (this is what I do), for others it's just a goofy time to brighten this chilling time of year, much like Christmas has long been. Some places may go far on the gore, but that's what they're bringing to it, it's not essential to the festivities.
