<adopts best fairground voice> here we GOooo!<br /><br />bad science:<br />multiple atomic bombs a mile or so away, no blast, thermal shock or radiation hazard,<br />worms dissolve in water, but don`t during the downpour at the end of book 1<br />another water riddle, where is all this water coming from that the Fremen are collecting to re-invigorate Dune and make it a paradise?, it`s a desert planet...no water, water is so scarce they recycle perspiration, yet they are collecting vast reservoirs of the stuff<br />they have vast technological resources but worms are an hazard to harvesters, why don`t they fit em with the jump jets the cargo lifters use to recover the harvesters?<br />and why bring back the harvester to the refinery when all you want is the spice?<br />why are they using troops rather than robots and turrets?<br />why don`t they establish scorch zones? <br />etc...etc...etc<br /><br />impossible social structures:<br />the Empire, the Navigators would own it, why tolerate a slippery oik like his Majesty (who they should know all about)<br />why send a second level navigator to have a chat?, just send some underling<br />the Harkonen would be too disfunctional to function at all, you couldn`t trust any one of them further than you could throw a worm, they would be in a permanent state of anarchy and mutual murder.<br />house of IX could not exist, in later books iirc they develop a mechanical starship drive, I`m sure the navigators would tolerate that (not).<br />Ixians would be like the Mentats, small groups employed by each house, not free to disrupt everything with whatever they come up with.<br />the sisterhood (and just about everyone else) has access to information about the future, but nobody see`s whats coming except in the vaugest terms.<br />the Fremen recycle water, we know all about that, but where do they get the food to feed all those people?, Dunes much vaunted ecology consiste of Worms, Fremen, Spice and a magical, ever increaseing, water supply,
