It's probably Woody Allen's worst film and is pretty dated. But it's not horrible and has some okay moments, like the moment when the projectionist stops the film to make out with an audience member. As a Woody Allen fan, I'm glad I saw it but wouldn't push anyone to see this one like I would some of his other films.
Particularité : les droits de ce film nippon de série B furent acquis par les grands patrons de l'Américan International qui chargèrent Woody Allen de le "bricoler" en rajoutant des scènes additionnelles et en y détournant le sens. Décevant et raté ! www.cinefiches.com
While it was, in 1966, an original joke and perhaps more amusing (whereas now it has been ruined by copy-cats--i.e. Mystery Science Theater), the gimmick doesn't age well, and only a few jokes are still very funny.
