The main problem is, most of these creators haven't done anything from which to have any basis to judge them on. There is there art available and none of them are particularly amazing, >Top Left
Has an interesting premise and the set piece actually looks pretty cool but it has the problem mentioned before. Combine that with no short/pilot to judge and there is very little reason to be excited, especially if you don't like the art style>Top-Right
essentially the same as top left except only the pet thing's design looks cool and the set piece is just kind of boring>Middle-Left
This show has the benefit of actually being out and I'm not a big fan, the art style is still the same we've been getting a lot of since Adventure Time, the writing isn't amazing, and the characters just aren't as likable as something like early AT.>Middle-Right
I actually enjoyed Twelve Forever's pilot, it seems visually interesting and the writing was decent, actually has characters that seem like they'd be cool to watch interacting>Bottom
The Infinity train pilot is basically nothing. The first car has her solve a simple puzzle, which at first seems like it could be a cool mystery/puzzle of the week but the rest of it past that point just has a "wacky world" thing which has been done better a million times by other shows and most of the jokes don't really hit, and it teases an overarching mystery which is almost all ways incredibly mundane bullshit that's been done better in other media like Naoki Urasawa's Monster, or Stein's;Gate, among a variety of others, and really in shows like this only ends up as an excuse for the show to string you along with episodes that aren't actually interesting but promise that there will be some satisfying conclusion that makes it worth it, and there almost never is.
