The Landslide
[13] Hero
Oh yeah, by all means they are all do-able on Legendary, Halo 2 is just the hardest. Halo 1 takes the cake though by giving the Pillar of Autumn level (the first level) the HARDEST moment in the entire game on legendary, specifically the stairway with a landing out in the middle of an open room that you have to battle up while being swarmed on all sides with elites above and next to you. That part is a showstopper, and is easily the toughest until the Keyes level, which is tough the whole way through.
