High School Musical 3: Senior Year - Trailer

Wow. What else is there to say? I watch this trailer (my first experience with the HSM phenomenon) and I have to wonder why people like it. That is rhetorical, I don't care that much. If you like it, I am happy for you, I just don't get it. The singing doesn't strike me as anything special, and those lyrics, ugh. Anyway, here's the trailer for the entry that brings the series to the big screen.
