What is it with glued together ARG games?

It's not that the game is horribly designed, but I'm looking at it after I beat it and think "What was there to love or like?" and I can't think of anything, not the narrative, design or even minigames.

I believe that if ARG design is to be good it requires enough length to make you invest in it. Pony island is short, sparse and gaping. Stick to Inscryption, this isn't anything like it.
