In keeping with the food threads and in the spirit of the season, share your favorite/least favorite Halloween candies, from back in the day or the stuff you buy yourself or Trick or Treaters now. Here's a few of mine:
Best 

Any full-sized candy bar (I've seen kids go out of their way to protect the one house that gave em from assorted prankery)
And a controversial one:

Root beer barrels. I love em, lots of people feel the opposite.
Worst:
Gross

Black licorice - just pay the 10 cents more and get the Twizzlers, jerk!

Crappy popcorn balls

Who even makes these? It is a mystery for the ages.
