One intriguing idea that the series introduced was that of an alien race that did not use technology at all, but "bred" or "grew" whatever it needed. So their ships are biological, their artillery is biological, and they have various kinds of fighting bugs as well. That was a clever idea.
But this episode introduced another clever idea as well--the idea of giant "sleeper bugs" that could sleep in space for perhaps thousands of years, looking like an asteroid, until one day waking up to head off to a new planet to invade. I don't know if that is a unique idea of their own, or if the writers got it from science fiction literature, but it is clever. The one downside is that they never really show this sleeper bug very well.
Something that I liked about this series that this campaign showed off well is that the story does not always progress in ways you would expect, but in some ways is more "real." For instance, at one point the troopers manage to get the Zephyr off the ground only to crash it only a short time later. I did not see that coming.
One downside is that the commentary tracks occasionally leave something to be desired. The filmmakers often re-cover the same background and explanations that they have on previous discs and we don't need to hear all of that stuff again.
However, portions of the footage seems grainy, like it was over-compressed, especially shots inside the dropship. I have heard this from others, but don't know if it was a bad batch, or that's the best they could do (...since this story arc was not originally meant to be released to DVD. And then, only after fan pressure.).
Oh, and am I the only one who is bothered by the fact the "M.I." logo on the Special Features menu is upside-down?? ...on every arc DVD? That aside, I would still recommend R:STC to every fan of Starship Troopers! Collect them all! I did!
