I can appreciate the creation-myth quality of the ending (and obviously, the amazing animation), but this whole post-Collide sequence jettisoned the best thing Homestuck had going for it, which was the character interactions and snappy dialogue.
It's understandable that Hussie would try to go out on a wave of images and emotions instead of words, but he swung so far in that direction that he ended up giving no closure to anyone's individual character. Hey, what was up with Karkat? Wasn't his arc building up to discovering his real role as a leader in the society to come? Wasn't there some noise about Kanaya, I don't know, using a newly generated matriorb to restore the troll race? Eh, who cares, TADPOLE.
