The Insectia series is NOT hard-core science, but as much a travelogue as anything else. The only problem I have with this series on DVD is that I have seen all the episodes on HDTV in wide-screen, and for some odd reason, the DVD release is in full-screen. The picture quality also cannot compare to high-def, and if they'd used the high-def mastering on this release, the picture quality would have been vastly superior.
I have seen reviews elsewhere, in which people were "horrified" that George Broussard euthanizes a few insects in the series, but really....what did they expect in such a program? What many people don't realize, is that by persuading native peoples to raise insects(butterflies especially) it gives them a renewable source of income, and thereby deters deforestation..the REAL environmental problem we're facing.
