Ageist? Ive dressed up and ate candy almost every single year and go to a Halloween themed music festival. If you think Halloween is for kids you're not trying hard enough
Any holiday can be overrated if you just decide its overrated. 
Valentines day? Sure, kinda overrated. 
St Patricks? Overrated as hell. 
Christmas? Yep, you guessed it, very overrated. Its not even Santa's birthday. >

Halloween? Underrated and ageist.
