I like it, I wish they would build on it, make it harder and add more rewards. But the problem is that the way the game is these days if casuals don't feel like they can participate in absolutely everything they cry a river and get that content nerfed.
It feels a bit like how it used to feel to solo old raids at the limit of a character's capacity which is probably the most fun challenge I found in WoW. I find it more fun and challenging than group pve content.
