YMMV / Goosebumps (1995) S3E5 "Click"

• Broken Aesop: While the aesop of "Click" is not to abuse power for one's own ends, the company that devised the universal remote is clearly setting up Seth to fail. First, giving so much power to a teen is just begging for it to be misused. They also warn him not to try to repair the remote by himself when he makes the perfectly valid point that he did try to go through the proper channels: they don't answer any phone calls and the address of the "showroom" they gave him was just some abandoned building. They also appear to be aware what Seth is doing at all times, so they could have intervened at any point.
• Nightmare Fuel: "Click" isn't particularly scary for the most part, but then comes the ending, where Seth, whose mind has been taken over by the remote, attempts to stop his friend from taking the remote by hitting the power button on him... but ends up accidentally turning off himself, leaving him in some sort of void. And just then the batteries die! Uh oh! The creepy salesman from earlier thanks him for trying out the remote and just leaves him there, calling out for help. An even darker interpretation, one that the short story especially leans towards, is that Seth literally shut off the world.
