I heard about this on the radio and it sounded like an interesting idea. Then I saw your post and that the lead was Patton Oswalt and I figured it was a doomed project. He has been ok in the small parts I've seen him but figured he'd be awful as a lead.
Then I saw the trailer and I was very surprised at some of the scenes they showed. Pretty impressive at least considering what I expecting. I doubt I'll plop down $10 to see it in the theater but will catch it on HBO or Netflix once it is out.
