I really don't understand the problem here. Everything of consequence was 'borrowed' from SS2; even bad ideas like respawning enemies. Most of Bioshock was substandard or derivative. That doesn't seem very controversial to me.
I alluded to the economic/political garbage in most of my posts. People being murdered for buying and selling things (smugglers) without getting permission from comrade Andrei. Industries being stolen (nationalized) because the head parasite wants it. Expensive circus freaks sent to recycle adam in the street instead of just paying someone to collect the corpses and doing it in private. None of it has anything to do with "free markets", "capitalism", or whatever the developers thought they were writing about. This was the only element they added to SS2 and it's completely ludicrous.
Bioshock turned out like Deus Ex 2, Thief 3, and the countless X-Com remakes - flawed games that don't compare favorably with their predecessors.
