The only ones I've seen are 'Manos' (the MST3K version) and 'Birdemic.' 'Manos' is bad, but 'Birdemic' is truly shocking.
...and terrifying.
Those are actually the only two I've seen as well. I'd say Manos is worse, just because Birdemic is fun bad. Manos is a painful experience, even with MST3K running over it.
