This is what the movie should have been!
As a big Jonah Hex fan, I was deeply saddened by how awful the movie was; both in terms of accurately representing the comics and character, and in regards to it just being a bad movie. That said, however, this little short is simply amazing. Keeps with the tone of Jonah Hex, doesn't do anything outlandish to try and make it more appealing... it's just a good story with good animation and action.
The only problem I have with it is how short it is.
