Birdemic. It's so bad even Rifftrax can't redeem it (believe, I loved Rifftrax with Pumaman) and it's got its own cult following. I think Birdemic 2 came out for that very reason...
you can look at the trailer on youtube. I just realized it's not as family friendly as i thought.
Go farther, Go further, Go harder. Is that not why we came? And if not, then why bother?
