I can't even imagine how this opinion works. The entire driving force of Homestuck is the sense of mystery, and how stuff is revealed bit by bit as you try to predict and figure it out. If you know the answers ahead of time there's no point in even reading.
Hussie calls Homestuck "A webcomic that is also a puzzle", and nobody ever bothers with a puzzle that is already solved.
