First, of all Overrated≠Overhyped≠Worst.
Overrated means something that has too much scores. This word is often used when comparing statistics. E.g. Steins;Gate has a score of 9.17, and a #3 rank, while I was expecting a 8.8, but that doesn't mean it's overhyped or it's the worst. It just means it just has too high marks.
Overhyped means something has too much hype, fans, or focus. This focuses more on people than scores. E.g. SAO has a lot of fans, but it has a very bad mark and score, so it's not overrated, and it's not really the worst when you compare it to School Days. It just means it has to much hype.
Worst just means the worst.
Overrated: Steins;Gate(0.37 points above estimation)
Overhyped: Bleach, Naruto.
