As a Hellblazer reader, I noticed a lot of changes. I still liked the movie. Just accept it for what it is and enjoy it. The ending (after the credits) was cheesy, but on the whole the movie was good. And I liked the Ellie scenes that were deleted, but I see why they weren't needed.
Team America: World Police was hysterical. I laughed and laughed and laughed. It was the uncensored version, so there was even more marionette sex! The deleted scenes were great too. I have the song "America, fuck yeah!" stuck in my head now. *grin*
