On the one hand, I can get behind a trailer that was made into a movie, which this allegedly started as. I can also get behind Rutger Hauer movies. And Rutger Hauer playing a hobo sounds delectable.
However, on the other hand, these wink, wink nod to the audience movies don't do it for me. Other than Big Trouble in Little China, I can't think of a movie that succeeded in purposefully parodying the B movie. I thought both parts of Grindhouse failed (though for different reasons. At least Tarantino attempted to give us something different. Rodriguez just gave us gore and copied the structure of every bad late 70's/early 80's horror movie. But since we were in on the joke, nothing felt fresh or original. I guess it's ironic that the best part of Grindhouse were the trailers, which of course led to the making of this movie. We live in a Catch-22 world).
Anyway, I assume there is an audience for stuff like this, so I hope it succeeds, if nothing more for the creators of the movie. I will say this - it's hard to come up with a better title than Hobo with a Shotgun.
