I hope they do Latin week...I usually find that one pretty entertaining.
I also like Country week because I like Country music, but not everyone's suited for that genre, so some usually do bad that week. On the other hand, some really find their niche in Country, like Phil Stacey and Josh Gracin.
I liked in season 2 when they did the movie themes night. I loved Ruben's "A Whole New World." I wouldn't have minded if they had taken a break from the 60's night this season...I usually find that week to be boring, but that's only my opinion.
What other themes would you like to see on American Idol?
