Yes, I saw Sin City in 3D, and yes it was a horrible mistake. The actual reason isn’t nearly as funny (that being that the only showing at a time convenient for Lex and I was a 3D one) but I still think it’s a film best enjoyed without that extra D. I’m working on a full review, but the short version is that it’s okay. I didn’t think it was as bad as the general critical consensus made it out to be, but it’s nowhere near as good as the first film. I’d say it’s worth a rental but nothing more.
