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.
Ho Yay: Between David and Mark. You'd think there was something there that David didn't want Kay to know about...
Nightmare Retardant: Posters for the film developed an odd tendency to give Gill Man a pair clownish red lips.
Strawman Has a Point: Mark may be Jerkass, but if they'd listened to him, they'd have wound up a lot better: If they'd killed the monster (who they knew had killed at least 4 people previously, at least 2 without provocation) they'd have been fine. If they'd have left when he wanted to, rather than taking pictures of the cave than the monster probably wouldn't have broken out. And if he hadn't gone underwater after David, than David would have almost certainly died.
