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.
In the review for Son of the Mask, Mike is shocked to discover that the Nostalgia Critic has reviewed Jaws 3D, a movie he has already reviewed. Now the Nostalgia Critic has reviewed Son of the Mask as well.
An Out-of-Universe example. The crash scene from Our Lips Are Sealed is so bad, it's actually kind of funny. MikeJ rightfully calls it the worst crash scene ever.
Squick: In Piranha 3DD, there's an attractive woman covered in blood and a decapitated head lands in between her boobs. It's pretty disturbing. What makes it even more disturbing is that it looks like the writers intended it as Fanservice.
