Due to the runtime this counts as a brony documentary and, as such, it is the best brony documentary.

Helpful timestamps:
Viewers with sensitivity should avoid: 29:21-29:31 flashing tiktok imagery, 37:13-37:39 bronies raving with strobes, 39:11-39:22 flashing gifs up on an LED screen, 48:28-48:30 a pony gets zapped with flashing magic, 1:09:38-1:11:10 some concert footage played behind credits.
