What is good to see in Shanghai?

Thanks for yr advice…
I am going to be in SH for the first few days of the Expo, and I’ve seen chaotic scene of mainland Chinese cutting lines and steping over each other for the expo trail day on the News. With the ticket cost over 800RMB ( orginally $200) I don’t know if it’s worth the “danger” since I will be back to Shanghai matter of 1-2 months.

How about good art scene? Do you know any?
