I do miss hand drawn animation. Some of the older animes I like are hand drawn. They're not exactly as smooth, but I feel that each one has a more individual feel and personality to them, it's something I miss in modern anime.
Pretty sure it'll be mostly 2D as Studio Mir is the studio working on it and they haven't really done any full CG shows. Interesting though how this is a Dreamworks project as their shows are usually based on their movies.
Like, it's very stylized, right? But the problem is that it doesn't feel as...fluid, I guess. Like, I enjoyed the TMNT 2012 series (I dropped it part way into S2 and dropped it. Good show), but the action sequences just didn't feel as fluid. Or...something. It was incredibly clear when the budget was cut, because the sequence felt significantly slower.
I dunno, it's hard for me to describe. I haven't watched
Beware the Batman or
Green Lantern The Animated Series, which are the two other action cartoons animated in 3D/CG that come to mind (recently). So I'm only speaking from one source. Also, TMNT did actually have some decent action sequences as well.
Granted, I'm not generalizing CG as bad for action.
Final Fantasy VII Advent Children, say what you will, but that movie has amazing action sequences. I just think that 3D/CG cartoons have a long way to come before they deliver, and I'm not prepared for someone who was part of the creation of one of my favorite fictional universes of all time to create a new series in that style. I'm just not.
