I think some people tend to put more "emphasis" on an episode when the episode results in a winning temple run or even a very good run. So episodes that do end in wins tend to be more popular even if the prior rounds were mediocre. With that being said, I agree that the rest of the "Livingstone" episode was pretty average and lackluster. The temple games were too quick and the Blue Barracudas just dominated them. And even then, the temple run is not that exciting.
And I enjoy the Imperial Wizard episode too. The temple games were very fun and one of the few I remember from my childhood. The legend was pretty interesting too, but it was also very dumb and racist.

The Green Monkeys were also a very strong team. And I actually don't mind the temple run at all. It was a tough layout and they still came close to reaching the Mystical Spellbook.
There are a few episodes I like where I can't stand the temple run but the rest of the episode was good. Judge Roy Bean, Sir Edmund Hillary, Lost Lariat, Icarus, Captain John Smith, Golden Pepperoni, and Lost Taj Mahal Turban had crappy temple runs but the rest of the episodes were great.
