Such stuffy provincialists. I've enjoyed Nick parrk's "labor of love" craft and brillianc expressed in Wallace & Grommit , but "Chicken Run" was every bit a work of his art.
Yeah the writing was more formulaic & polished , like Pixar's "Toy Story" or "A Bug's Life", but it brought more deserved attention to Nick Park's artistry which is a job well done and any *purist* grousing seems petty by comparison. His artistry remained intact and got the warm reception it deserved.

Note that not every episode of "Wallace & Grommit" is a masterspiece either. That episode script where they go to the moon to taste the green cheese was a "strained" efort to say the least and came off more as an experimental demo piece.

I've also enjoyed the pre-Wallace & Grommit anthology of his earlier work including the brilliant short interviewing the zoo beasties that won him a well deserved Academy Award.
What's so brilliant is when you catch yourself realizing that it's all this clay talking at you and it just gets funnier with every frame.

Really looking forward for new work by Mr. Nick Park.
a fine artist and mastewr of his craft in the tradition of a Jim Hensen and that ain't faint praise.
