TV's most successful reality show celebrated its 20th (!) season by bringing in the big guns. Every week's Tribal Council was suspenseful, and the challenges (resurrected from previous seasons) were spectacular—often thanks to Boston Rob's incredible dominance. In fact the game's greatest showdown occurred on a single tribe, between Villains Rob and Russell Hantz. If the rumors are true that they'll be squaring off again, we can look forward to another epic season.
