Random Riddle: In the Dark

The dark you’ll be in, figurative and literal
Failing the correct frequency digital

Though sitting and staring may sound boring
Strange new worlds may you be exploring

As I entertain you, time will quickly pass
The images you will witness, all seen through glass

The first’s main subject may be a monstrous creature
Comedy or intrigue may prevail in the second feature

What am I?
