First one was good, especially if you understood the themes Heinelan had in his book - the guns, bugs, boobs, etc... were really secondary to the exposition of life in a future fascist state (for me at least )
If they can go back to that universe and expand on differences between 'civilians' and 'citizens' to really delve into what the political/social message was in the book and introduce some more guns, bugs, and boobs it could turn out decent.
Then again, it could be like ST2 - horror/slasher movie set in a space outpost or something? bleh
