OK maybe detailed was the wrong choice of word, more the rest of the classic muppets have something about their look ... lets call it a trademark Henson look, that means they kinda fit in with the rest of the family.
It has to be said, these new Muppets do look distinctly different from that. I do agree about the personality thing, and I felt Angelo also lacking that big time so it made the character even less likeable. We haven't seen Walter "in action" yet so i'll reserve judgement.
I don't get people who are Muppet fans taking every tiny thing that isn't 100% positive said by another fan as them just trying to criticise for the heck of it. There are some very valid points here, and everybody's opinion is as important as the next. It's meant to be a discussion forum, even the people actually making this stuff sit around and critique it in an effort to make it better, sometimes even here. I'm super looking forward to the film, I just want it to really be the greatest Muppet Movie ever!
