Cool cartoon.
NOTE: I'm under the assumption here that you're referring to the trailer, and not the Futurama clip. If you are referring to the Futurama clip, then disregard the following. I'm also assuming your comment was a sarcastic one, referring to the excessive amount of CG and cartoon-like imagery.
That's an interesting take on it. So, if it had of been completely CG - that would be fine? Don't get me wrong, I'm not ragging on your post, but I'm wondering when the combination of live-action and animation became an issue. This isn't a new thing, movies such as Pete's Dragon and Mary Poppins combined animation and live action decades ago. Animation evolved into CG, and now that combination has basically taken over. For me, it's fantastic that animation has evolved to the point where it doesn't stand out as animation, but rather blends in well with the live action components. It can make a movie look synthetic, yeah. But when you have a movie about a man on Mars fighting alongside an alien race - it's already synthetic.
I believe it's spelled Kashmir btw
Uh...yeah...I knew dat.
