Eeeeeeek...look, I'm a filmmaker too, so I'll try to be constructive...1.) get a better camera man. What's he doing the whole time, scratching his butt? Keep the camera still for Christ's sake! 2.) use more than just a key light to light your "actors" 3.) don't film dialog with the "actors" backs to the camera 3.) bring in your zombies before the 43 minute mark 4.) have at least one other person review your script before you shoot it, multiple drafts can be effective in developing meaningful dialog 5.) pay for better ADR services...if you paid even $1 you got ripped off 6.) give me the name of your agent ... if he can sell this piece of poop, he can sell ANYTHING!
But keep trying...I think you'll nail your next one...as long as you eed tips 1-5.
