Wow, the silliness abounds today.
Tolkien himself has said repeatedly (as if the text wasn't enough) that Hobbits are a variety of Man-kind. In Middle Earth, there is really only a small variety of races. Elfs, Men (including Hobbits), and Dwarves - the rest (Trolls, Orcs) are all derivatives of these, with the exception of the occasional Istari or other supernatural being.
Hobbits should look essentially like people - keep in mind that Jackson has read the series more than you, Christopher Lee has read the series more than you, and Alan Lee has read the series more than you (otherwise you would have known that Hobbits look like people). Sure there are changes, but these guys know the text and they know what they're doing to the degree that, while we may not like some of the plot changes, they will be faithful to such fundamental things as making Hobbits "look" like they should.
Also, please keep in mind that this movie hans't even been released yet, and you are already denouncing it.

MOVIES SHOULD STAY AS MOVIES
BOOKS SHOULD STAY AS BOOKS
This is so assinine that I really can't even think of anything appropriately mindless in response.

If you are so fixated on everything looking like you think it should, and consider your vision the definitive one, then I recommend that you stick to your books, toss your TV and never leave the house, lest you contaminate the purity of your righteous vision.
