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.
Broken Base: A mild example but some people were skeptical that thechineseroom was developing this game, this mostly come from fans who didn't like Dear Esther. Many of the fears have dissipated though when Frictional Games said that they are still going to be the publishers
Now that the game has come out, changes to mechanics has brought this issue up again, see They Changed It, Now It Sucks below. It seems another one is that if Frictional should have had given thechineseroom as much as they did in the final product, and if it makes the game better or worse.
There is also a group of people that are miffed about how the game doesn't feature the changes that Frictional promised. The monsters don't act much different from the ones in the previous game. And the promise that monsters don't disappear doesn't even matter much since there are only a few in the game. Also despite promises to make the game more open, the end result is very linear compared to The Dark Descent. Again, whether or not if these changes were for the best or if they were because of thechineseroom's influence is a heated topic.
Critical Research Failure: Mandus apparently got the Pig Mask while exploring an Aztec temple. But pigs aren't native to the Americas (peccaries are, but the mask clearly depicts a domesticated pig), and the design on the mask is very much not Aztec. It's more similar to Haida designs from North American tribes, which is a pretty big distance to get wrong. For a game that obviously spent a while on researching industrial England, this seems less like a mistake and more like "Screw it, make it look foreign and intimidating".
Fan Nickname: From the teaser trailer alone, the pig monster earned the nickname of Piggeh.
Hype Backlash: Many fans of the original were naturally excited when the sequel was first announced. Upon the game's release, fan reactions became... mixed at best. See Broken Base for details.
It's Short, so It Sucks : This game clocks in about 3 1/2 hours of gameplay, which was about half of the original Amnesia. Because of this and the removal of an inventory, many fans have felt that this game is more linear and doesn't encourage you to explore nearly as much.
Love It or Hate It: People either hate it for it's streamlined gameplay, short campaign, and lack of scares, or love it for it's complex story and voice acting.
Narm: Mandus's journal entries are written in an often epic, pompous style that comes out as unintentionally hilarious - and makes you doubt if he's really serious about saving his sons.
"How can a man shit so much blood and still live?" Sounds more like something you would hear from South Park than Amnesia.
On a similar note, Mandus's threat to the Machine.
Mandus: I will rain excrement into your very soul.
The Engineer, post reveal, can really seem like this, with just how hammy he is sounding, more comical than threatening.
The Engineer: MORE PIG! MORE PIG!
Also the fact that The Engineer ultimate plan is to take over the world with an army of manpigs sounds like, on paper, something from a Silver Age comic.
Shocking Swerve: It seems like the scene after Mandus activates the machine, and The Engineer releases the manpigs onto London to bring about The End of the World as We Know It has been getting this reaction from fans, especially those who were used to the subtly of the game up to this point.
Many fans have been outraged by the removal of the sanity effects and the inventory.
That, coupled with the roughly 3 1/2 hour play-time (barely half of the first) has also led to lower reviews.
Ugly Cute: The pigmen aren't as deformed as the creatures from the first game, they just look like some kind of vaguely humanoid pig animal. Murderous grotesque perversions of nature though they are, they can be seen sitting at a table to eat messily or playing children's toys, which gives them a surprisingly sympathetic child-like innocence.
Uncanny Valley: The manpigs invoke this trope, not so much by their appeareance than the way they move. When you see one for the first time, its stooped, three-legged gait makes it hard to tell if it's an animal that has been turned monstrous or a person that has been turned animalistic. It's a minor Wham Moment when you see one standing up for the first time, revealing that they are indeed fully humanoid.
