a lot of positive, but the story is too constructed

the 157th episode of the Three Investigators offers much that is worth to praise himself: sonderliche and interesting secondary characters (giant, gizmo), many scene a great atmosphere is created, the music I like this time particularly well and across the board very good speaker cables , and now the but: all the action seems to me much too contrived.
