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.
Moral Event Horizon: Victor still keeps trying to kill the Were-Rabbit even though he's aware of his identity as Wallace If anything, discovering the Were-Rabbit is the man who's seemingly stealing his girlfriend away from him makes him even more determined to kill it.
Nightmare Fuel: Both transformation scenes. The second one especially, where Gromit is pinned against the door as Wallace is transforming and desperately begging him to help him.
