Happy feet is a movie that was hyped quite a lot.
And what it actually was, is a technic flick: "Look what we can do". A proof of statement. A studio showing off.
Yes the ideas were cuddly, but the portraied animated figures just couldn't deliver. Yes see it but then you will be in my place, thinking of how truly cute this could have been in drawing with more comic style. In I Happy Feed they try too hard to get that penguin as close to real as you could with their PC's. And that's what ruined it. You do not want a "real penguin dancing around".
Why didn't they do it the other way? Because another studio was doing a penguin movie with comic-style...Hollywood...what else
