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.
Narm: Some of the more dramatic scenes are a bit overwrought, and Nicholl's death can be downright goofy-looking.
Averted in the film with a Gory Discretion Shot - all we see is a blaze of slow-motion gunfire from the German guns, and then no more Captain Loki.
The scene after the British cavalry charge the German camp and the heavy guns open up. All these horses are charging right past the guns, you don't see a single rider on any of them, and as sad as it is all you can do is start laughing about what incredible shots those Germans are. Must be horse lovers. (Note: Horses are huge targets compared to the men riding them, and a dead horse=a wounded and/or ineffective cavalryman.)
Nightmare Fuel: The war scenes, the gas attack in the German Trenches, Joey getting tangled up in barbed wire and the horses jumping over the German Lines in the forest without their riders during the failed British cavalry charge.
Accidental Nightmare Fuel: In the movie, after Joey finishes getting tangled up in barbed wire and he is lying on the muddy ground, there is a lightning flash and for a single frightening moment, you can see what appears to be a Slasher Smile on his face. It's really a normal horse expression, but it still looks rather scary.
No Yay: Albert's devotion to Joey is implicitly compared to the love Taylor has for his girlfriend.
Signature Scene: For the movie, it's either Joey at the end of the film in the sunset, the attack on the German Trenches, Joey dashing through No Man's Land, Joey getting tangled up and freed from barbed wire or Joey jumping over a British Tank.
