* Spectacle: A public display or performance that is intended to be impressive and awe-inspiring.
* Frightening: Causing fear or alarm.
Therefore, a frightening spectacle would be something that both draws your attention with its grandeur or unusualness, but also makes you feel afraid or uneasy.
Here are some examples:
* A massive storm with lightning flashing across the sky. The natural display is awe-inspiring, but the power and unpredictability of the storm can be frightening.
* A large, menacing animal. The animal's size and physical presence can be both captivating and scary.
* A horrific accident or disaster. The scale and destruction of the event can be visually shocking and terrifying.
The key is that the "frightening spectacle" combines these two aspects:
* The visual impact of the event itself (the spectacle)
* The emotional response of fear or unease (the frightening aspect).
