Here are my least favorite episodes on Legends. I refuse to watch any of these episodes except when I am using to do something (like the Legends episode ranking system.) These episodes have nothing redeeming about them.
1.)
The Cracked Crown of the Spanish King (long and painful moat, pathetic temple games, boring and pathetic temple run, and just plain and boring in general. Nick GaS used to play this episode ALL THE TIME!

My most hated episode in the series.)
2.)
The Golden Cricket Cage of Khan (Nothing redeeming about any of the rounds of this episode and the temple run is so bad that its laughable.)
3.)
The Bifocal Monocle of One-Eyed Jack (Stupid legend, another pathetic temple game performance, and one of the worst temple runs on the entire series.)
4.) T
he Snow Cone of Mt. Kilimanjaro (Stupid artifact, stupid legend, and another pitiful temple run with incompetent players.)
5.)
The Keys to the Alhambra (Admittedly, I kind of have a soft spot for this episode since I remember it from the original Nick days. But still, the temple game tiebreaker was depressing and the temple run is so hard to watch.)
6.)
The Marble Armrest of Xerxes (Another episode that Nick GaS overplayed and the Green Monkeys were one of the most undeserving teams to enter Olmec's temple. The only redeeming part though is the temple games were sort of close and the legend was interesting.)
7.)
The Lost Lion Tail of Little John (Um yeah, the Purple Parrots only got to the temple on a Silver Snake screw-up in the last temple game. And then they blow their whole load in the temple run.)
8.)
The Lucky Pig of Amelia Earhart (Kristen is the one that makes this episode look bad. She didn't even try in any of the rounds of the temple. It was Scott that carried this team through the whole episode. And the temple run is so bad even if it was a hard layout.)
9.)
The Smashed Printing Plate of Frederick Douglass (Just an annoying episode in general to watch. The temple games had two instances of cheating and the temple run is hard to watch with the incompetent players and their big mouths.)
10.)
John Henry's Lost Hammer (The other rounds were average, but the temple run was so mediocre. How do you not know what an actuator is?)
