irwin allen be great . all of his tv show have a great pilot and or first episode . the rest be basically rip offs of his other show . a few episode of swiss family robinson be rip offs of his old tv show . one episode of swiss family be identical to an episode of land of the giant when a member of the party need an appendix operation . the show be high budget and too expensive to continue . irwin lose his touch with tv show after the 60 . the acting be strong with martin milner . child star get there start with this show like willie ames and helen hunt . one bright spot be when irwin allen incorporate his disaster scene like a typhoon and a volcanic eruption dub him the master of disaster .
