I've only seen Dark City and Serenity of those five so I can't really judge the other morally, but being a person on the internet its my obligation to say that the other suck lol jk like I said never seen them so I won't judge. Anyways, of the two Serenity is my go to movie of choice. Dark city is a once every two years movie, but I can watch Serenity several times a month.
