Not that I expect anything less of Hollywood.
Someone in the forums put it best:
On one hand you can make it true to the cartoons and comics, thus making the old fans very happy but probably not winning many new fans....and that, kids, means merchandising, and money-making. Screw integrity, it's all about the Almighty Immediate Dollar. Fuck you.
On the other hand you can make it all CGI-esque and infantile, thus winning over a new batch of young kiddie fans but alienating, and possibly disgusting the old loyal fanbase.
But they'll all go and see it anyway just to see what it's like.
So that decision's been made then. Make a new crappy version targeted at five year olds. Nobody over the age of three is gonna like it, but at least they'll pay to see it.
