Considering the key "element" in BioShock's narrative was the players illusion of choice (as in he didn't really have any beyond saving/harvesting the little sisters & that was more of a calculation than a choice) I think it would be incredibly hard, nigh on impossible, to recreate that in Film and not only because most people who played it already know the twist. I bought and started reading the tie-in Novel - Rapture. Didn't get very far into it before being distracted. Like any other tie-in if the film took place in the days leading upto Raptures downfall it would probably do alot better. As it stands now, I agree with the above, just drop the title.
