1) How much (page-wise) do you think the pilot will cover?

I think the cliffhanger of Act 1 with John's house in the void is too perfect for them to pass up. They're for-sure gonna slash that thing down and fill a bunch of the gaps with Rose/Dave/Jade stuff, but I feel it is very likely that they'll reach the meteor.

2) Do you think it'll be good or bad (in your opinion)?

No idea! The direction and visuals seem great so far, so it's all down to whether the script holds up.

3) What's the deal with KARKAT? What about Jade? AH???

I've heard tell that Karkat's appearance was animated specially for the trailer, and it would not surprise me if Hussie is the same way. Jade is kinda right on the edge, but I think it's possible that Karkat is just a voice role for now. Hussie isn't credited with an actor at all, I think it's possible they're not even in it.

4) How long do you think it'll be?

I'm assuming you mean a prospective full-series, since we know the pilot is eleven minutes. I honestly have no idea, and I'm not even sure if the pilot will give us a good idea of how truncated the larger story would be. If it were a full-scale adaptation with no stone unturned or even some things made more in-depth, I'd give it sixty-ish 22-minute episodes, but that's a pipe dream. The concept of ten seasons of eleven minute episodes is also completely ridiculous, so I genuinely can't imagine more than four seasons.

5) Will there be musical numbers?

What? no.

6) Do you think children's content farms will capitalize on it? What do you think will get crossed over with Homestuck against its will in Minecraft SFM Nursery Rhymes?

If it's on youtube, yeah. Didn't take long for bootleg plushies, after all.

7) What do you think new viewers will think of Homestuck?

No clue, depends on if it's any good. I bet a lot of people will try to read ahead and get turned off by how much text and fucking-around there is, though. I do worry that the density of weird game mechanics and arbitrary rules about character communication will make it hard for newcomers to get into either way, though.

10) What do you think of the voice acting, or the animation so far?

VA work seems fine. Not great, but not unprofessional or anything. I am worried about a few of the John lines, not because Toby is doing a bad job per se, but because they sound unnaturally-written, and I'd hardly say Hussie crafts dialogue that feels very flowing to pronounce aloud.

The visuals are genuinely pretty great. Not my preference, but skilled in every way. I know people don't like Spindlehorse's usual style, and this isn't totally divorced from that (though if you compare them side-by-side, they're definitely distinguished enough), but to act like this is anything but polished and professional is very silly to me.
