I actually didn't like the last episode as much. It was too predictable, and they seemed to have changed out the musical numbers for bullshit teen melodrama. They really need to deep six the "I'm pregnant" subplots and ice out the annoying secondary characters.
I was cringing a little bit during the football dance. I guess that was the point, but it did feel a bit predictable and over the top in an embarassingly funny kind of way. Also, Maybe this is just the problem with watching one episode a week, but I thought this was a musical. Let Rachael Sing, and part of Taking Chances doesn't count. I like the musical element of this show and this last episode felt lacking in that department.
