All 5th gen creepypasta's I've read haven't been that good, at least not anywhere near the level of creepypastas like the Laver Town ones and Snow on Mt. Silver. Although to say, I've still yet to find a good one for any of the other two generations as well, so 5th gen is not alone.
There was also a creepypasta competition here on PC back in the GT of 2010 I think, so we have a lot of creepypastas made from the members on here. First part of the thread is just a collection of creepypastas they've found, but around the later pages the creepypastas should all be gathered together in one post ^^
