Call outs, sounds, and characters are very different, being based off the comic book, and not the movie.
Game play has some improvements...like a motorized DocOck, upgraded magnet, cliffy's, etc.
I've been told it's better built, but I never owned the original. Comes with a shaker and LED's standard.
However, I think it boils down to whether you like the theme and cosmetics really,and want to pay a premium for that.
It's priced like a premium in the $9500 plus tax range. Original was thousands less, but times have changed since 2008.
