I don't know how it's so difficult for people to understand that once you remove the original creators of a thing and hand it to a corporation, said thing won't work again.
As usual, to each their own and all that, but it's just common sense. But anyway...
A Genndy Tartakovsky animated series.
Or...
What this artist produced a few years back >
Patrick is a friend of mine and I gave him a hand during the making of that clip. He is supremely talented, and
the right person for this in the same sense that Bruce Timm was ideal to nail the look of an animated Batman in the 90s. People in some animation circles consider his design old-fashioned, derivative of Don Bluth and a bit out of touch for today's trends. I disagree. Indiana Jones
is old-fashioned, and there's a sense of elegance and nobility about his adventures that only 20th-century style 2D animation would capture. If anything, it could be produced in CG with an approach similar to Arcane or Paperman so it still preserves a painterly look, but freeing the camera to mimic Spielberg's visual language better. One way or another, the look that Patrick produced is just right for it.
It would've been great to see him art directing an Indy cartoon back when Lucasfilm was still independent, under George Lucas' supervision. An animated series is indeed the one thing that hasn't been done with Indiana Jones yet and it fits the property really well. Nowadays, it doesn't really matter though. Whatever they do, it won't feel authentic. It just can't.
