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: Splatterhouse
Anti-Climax Boss: Justified - the Mask wants to take revenge on the Corrupted for an eternity of slavery, so he summons them - and instead of putting them in Dr. West's super-bodies, the Mask traps them into a relatively weak body made up of the corpses of Rick's victims, forcing them to face an humiliating (but not total) defeat.
Freud Was Right: One of the monsters in the 2010 version, the Abhore has a huge, bloated right arm that leaks a.... weird fluid whenever it's swung around. Possibly lampshaded by the mask.
From the 2010 game comes the Aegis: a tentacled horror that never attacks on his own, but makes all other monsters invincible, actively runs away from you and teleports away if you get too close, forcing you to use the shoulder tackle to pin him down. And since the thing LOVES to hang around exactly in the middle of enemy crowds...
The Blue Skeletons. They can slice off your arm in one slice, and kill you in two. And when you're unarmed they take forever to kill. And towards the end, they start coming in groups.
Most Annoying Sound: The Giant Boreworm in the third game. It's horrendous laugh will echo through your head for the rest of the game.
Player Punch: Frequently, especially in the third game.
So Okay It's Average: The 2010 game, when it's not bombarded with too much criticism, is generally considered this, the story received quite a lot of praise, however.
