I watch the original series because Dream Valley is spectacularly dangerous.

This guy spent months watching both series of my little pony and, although the ponies generally have a live and let live policy, almost nothing else is calm and peaceful. To quote:

So, to sum up:
3 attempt to destroy Dream Valley (Tirac, Porcina, the Gloom Volcano witches).
3 attempts to enslave the ponies (Katrina, the scree, the duchess. Arguably Grogar).
2 attempt to destroy Dream Valley in order to rule it (Squirk, nazi penguins).
2 attempts to conquer Dream Valley (Grogar, the flories).
2 attempts to drain the life out of the ponies (Arabus, Somnambula).
One attempt to hick all the world's magic (Lavan).
And so much more.
Harmless lovey-dovey cartoon my ass. Dream Valley is constantly out to kill you. It's like Australia, Sunnydale and Ravenloft met at an orgy, and spawned this abberation, then woke up in the morning and freaked out when they realized Care-A-Lot and Disneyland had also participated
