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: Hemlock Grove
Base Breaker: Second season character Miranda, going by comments on the show's Wiki. She's either an interesting and sympathetic Na´ve Everygirl, or an annoying snoop who sticks her nose into things that aren't her business. Her detractors also aren't a fan of her more sexually active lifestyle in contrast to Letha.
Peter's first on-screen transformation in the TV adaptation definitely qualifies. It includes Peter's flesh being flayed off, his teeth falling out and then his wolf form proceeding to eat some of the flayed off flesh. Suffice it to say that Netflix did not skimp on the special effects.
And then there was the part where Christina (in vargulf form) ate Peter's face...
Perhaps that's exactly why they did it. Most, if not all, of the characters killed off at that point were only there to be killed off, you never got an emotional bond with them or knew them at all. Whether you liked Chausser or not their death was a slap to the face, no one saw it coming, but considering Pryce's surprising statement we might see them again.
What an Idiot: Norman in the second season finale. Basically, he had the perfect opportunity to kill Olivia and end her crimes once and for all when she's weakened, but decides not to. She recovers her strength, and then kills him herself.
The Woobie: Shelley and to a lesser extent Peter. Both of them get far more hate than they deserve considering they are generally good, helpful people.
