1958's "The 7th Voyage Of Sinbad" (with its creaky pre-CGI effects) is definitely one of those Fantasy/Adventure pictures (from yesteryear) that (as an adult) you are really gonna have to be willing to cut it some slack, otherwise, (in the long run) you're probably better off passing on giving this one a view.
Clearly geared to entertaining youngsters (who have very low demands on story coherency) - I'd say that the stop-motion monster effects (created by the imitable Ray Harryhausen) were, without a doubt, the real highlight of the action in this one's story.
