The Adventure of Denchu-Kozo

SF time travel weird story. 8mm restored, but still means that image is blurry, sound is mostly desynchronized, it's weird. You can never say if the image is bad on purpose as a special effect or if the original film was damaged. Action almost always looks bad. But all that is the medium's fault, not much can be done about it. However, there's an idea and a basic scenario which is good. Result is not that bad given the means available. The concept is original, though the main plot twists are painfully obvious from the first second, so much that when the protagonist discovers it you're like "wait what ? He didn't know that ? It was supposed to not be known ?" Action is hard to follow, hard to tell what happens in the "fights". Given when and how it was done it's pretty watchable as a curiosity.
