Was a big fan of the live action movie actually. Yes some of the changes are a bit jarring at first, but to me they made sense.
Making Gamilus into bugs sucked the drama out of the film. What was good about the TV series was that Gamilus looked human, this effected the crew. It made it difficult to fight an enemy similar to them.
Making them bugs was just computer game shoot-em up crap.
It's not entirely clear what they were, but I don't think they were "bugs". They had the ability to scuttle around, but were sort of bipedal and could run like humans. The novelization calls them "Gamilasborgs". They may have been an artificial race created as host bodies for the crystalline Gamilas life form.
