Depends on what your definition of 'suck' is. Something ALWAYS happens on Halloween, it's the one weirdness that's predictable - but it itself is unpredictable. Last year, it was horror movie monsters, when I was 12, I swear to god, everyone turned green.
You'd better be coming to my wife's halloween party, though. Notable personages. (Though if you were planning on going as something fictional, I don't think she'll throw you out.)
