I had my students watch glee during my summer and winter camps last year and it was really successful. The advanced and intermediate level student watched the show with English subtitles, the low level students watched with Korean subtitles. The worksheets are used to make sure the students pay attention, help them understand the content of the show, and teach them more about the culture they see during the show. If you discuss the summary and cultural material with the kids before the show, and the questions and character identification after, the kids understand more and have more fun with it. The whole thing takes an hour and a half to 2 hours.
[Mod. Edit: I changed the title to indicate the level, and moved it to the Summer/Winter Camps board]
