Wasn't anyone else bothered by the fact that this galaxy-trotting, warp-drive (or whatever) using, thought controlled weapon-inventing civilization (the members of which nonetheless act like slavering hyenas... and stupid hyenas at that) had come umpteen light years to a planet riddled with pesky "insects" to mine gold, the reason for which we're told is that "it's as valuable to them as it is to you", when they could have stopped off at pretty much any rocky planet, planetoid or asteroid belt and mined away to their dark hearts' content and with no interference from indigenous populations? Or that, given the ability to vaporize huge chunks of earth along with entire herds of cattle, vegetation and any of those afore-mentioned pesky insects, they wasted their time rounding the latter up from the sky (and, let's be fair, likely killing anyone so whisked in the process) to probe their "weaknesses"? Exactly what weaknesses would those be that they'd need to determine? These are just the "plot's" most glaring deficiences, imho.
