It is strange to come back from seeing this tonight to see School of Rock getting good reviews, since I always say I rather creatives aim high and miss than aim lower and get a bullseye. Sometimes the former is less easy to sit through than the latter, although I still stand by that desire.
I watched the movie a few days prior to going, and I don't think it made much of a difference. What little you were able to easily sort out based on the movie wasn't very elusive to begin with...
I was also mixed on a lot of famous Bowie songs appearing, as the familiarity didn't make it mesh with the material any easier/better for me.
It's a pretty high-end problem to have that talented cast sing Bowie songs and make performance art for you for two hours, though.
I wouldn't recommend anyone without tickets to knock themselves out trying, though, heh.
