These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Halo: Evolutions
Crowning Moment Of Awesome: Cole's entire life could possibly count as one, but arguably his actions at the Battle of Psi Serpentis, which Which he single handedly planned and orchestrated a situation which lured 200 Covenant ships to him, close to a gas giant which he nuked en-masse to initiate a mini-nova that obliterated everyone near it. And ONI has enough evidence to be 89.7% sure he's even escaped THAT and STILL LIVES.
Moral Event Horizon: Gage in Dirt was faced with the prospect of his friends committing one by abandoning a class of children and their teacher they came across to their deaths by the Covenant all for the sake of robbing a bank and going AWOL. Subverted by Gage's heroic actions.
Iron Woobie: Gage Yevgenny. He didn't join the ODSTs for nothing.
Narm Charm: The entirety of Dirt is Gage Yevgenny stopping some random guy to tell him his life story as he dies. But it's still very moving.
Squick: The graphic representations of the Flood in Mona Lisa and the Brute treatment of humans in Stomping On The Heels Of A Fuss.
