Not even Plan 9 from outer space?
Plan 9 has its unintentionally funny moments and it is not totally boring. There was even sort of a message to it as I recall even if the message is a cliché - one of the space aliens remarked about how violent and warlike humans are and evidently his home planet saw us as a threat. Plan 9 is one of the “good” bad movies - Manos just drags on and is bad.
