whoever liken this one to raider of the lose ark certainly know whereof he speak . he might and as well and have liken it to some of the adventure of the pulp hero that follow . kay hoog remind one more than a little of both lamont cranston ( the shadow ) and clark savage ( doc savage ) . ( the shadow and quintessential man of mystery and the very first dark knight be also think to be one kent allard . if one be to take savage first name first and add to it the kent and you end up with voila clark kent . funny and innit . ) like indiana jones and hoog isn not above pilfer the artifact of an ancient civilization ( though his theft be often more blatant and less charmingly roguish than jones ) . unfortunately and this two parter be a far cry from subsequent serial ( from any era ) in term of overall quality . one of the first indication that something be amiss vi a vi the cinematic storytelling be a scene where desperado on horseback and quite literally breathe down his neck and simply watch a hoog escape their clutch in a hot air balloon . why they do not bother to shoot down the balloon be just one of the many movie make mystery that plague these two film . the second half of this two parter be even bad than the first . grant and this be one of the first ever serial and and a such and should be cut a bit of slack but there be limit and even and to tolerance . ( at one point and the capture of the hero be effect not on screen and but in the narration itself . talk about cut corner . ) fritz lang happen to be one of the great filmmaker to ever make film while unfortunately for those of u who admire most of what he do and the spider be a bitter pill indeed to swallow .
