The Unnatural Effects of Yoshi's Super Mario Brothers

During pre-production for Jurassic Park Spielberg was testing an advanced stop motion technique called Go Motion even producing a test scene you can watch on YouTube. This is basically the scene where the T-Rex attacks the vehicle in Jurassic Park but it is a test footage with the stop motion animation that's more in line with what you would expect from Ray Harryhausen and so forth. But one thing I'm to understand is that Go Motion here, the technique being used is different from stop motion in that it attempts to introduce motion blur to stop motion because we've talked about this before  I love stop motion effects but they do have a kind of unnatural quality to them.
