Yeah, I agree with what your saying and I think thats its kinda stupid that whoevers in charge thinks that CGI should only be animated in the goofy styled animation that they use. I mean, I suppose they think thats what their audience likes but really, if you never show them anything different, how do you know they actually like it? You never know, they might like something else as well or even more than the cheap movies with cows and barns.
Well, you have to consider the demograpghics in this case. Who is more willing acccept something thats not firmly grounded in reality as opposed to reality. The answer is kids. Kids will more or less accept anything that jumps, spins, walks, talks, and moves in a humorus fashion. Adults however are more critical of these points. Adults more or less accept themes that are better grounded in reality, as in the case of Jurrasic Park, or Terminator for example where the themes are more of an adult nature that portray a more believeable setting as opposed to a less believable setting.
