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: Deadly Friend
Narm: Keep in mind that the basketball kill scene is played for horror value.
Special Effects Failure: The decapitated body in the infamous basketball death scene is clearly a puppet. You can even see what looks like the outline of the puppeteer underneath the nightgown.
The exploding head itself is also very obviously just a hollow dummy head.
