Gotta disagree about Amy Adams' Lois, I thought she was great. Margot Kidder was alright, And Kate Bosworth didn't appeal to me at all, so, Amy Adams, IMHO was the best Movie Lois, and I am definitely looking forward to her in a second movie
I just thought she was super bland, and the plot was working way too hard to make her feel "important" (why the hell did Zod want a random human woman? Why did she go with the military people?). She also figured out Clark's identity by the power of plot convenience. She was fairly pointless, and bland. Every single Lois I've seen (except the woman in the horrible Lois & Clark show) was better than her, but it was admittedly more the writing's fault than Amy Adams. I think she could be a decent Lois, just let her character be written by someone who isn't incapable of writing a good Lois.
