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.
Memetic Mutation: The film's regular scheduling during the early days of HBO caused a joke that the channel's name stood for "Hey, Beastmaster's On."
Nightmare Fuel: The people turned into wild madmen with glowing green eyes, the birdmen who eat by wrapping their wings around people, and only bones are left.
In the second movie, when Arklon betrays his Dragon, she curses after him as he drives away, screaming "May tarantulas grow in your mouth!" She's a witch, so it happens. It's played for laughs as Arklon makes a face and then spits them out, but it's still insanely gross.
The Scrappy: Jackie. Apparently we wouldn't understand she was from the present day unless every single line she says featured a forced pop culture reference.
Sequelitis: Both sequels are considered to be pretty terrible, although the third one is commonly felt to be a little better than the second.
