It was a matter of priority.
I now present Part 1 of this (hopefully) ongoing discussion. My observations and analysis derive mainly from the drafts, but I also took the time out to re-watch the movie. The wall of text I totally left in the discussion thread attempts to contextualize the film in the scripts from which it originated, looking at some of the over-arching themes, similarities, disparities, plot-holes, etc. The discussion aims to look at what the film could have been, what it became, and why.
By the end of this first post, I actually felt a kind of sympathy for the film. It's a little bit unsettling...In the meantime, here's a excerpt of my analysis of the second draft and its revision:
After reading both Bennett/Runté drafts, I admit I came away with a new appreciation for the screenwriting of this film. It goes without saying that there are darker, more adult streaks pervading these scripts, which I suppose helps if one is trying to appeal to teenagers. But the thing which really struck me was the political commentary and satire. The reinforcement of neo-constructivist Koopa propaganda and the conception of a dystopian, parallel Manhattan smacks of anti-Soviet and anti-totalitarian sentiment. This script was written in a very recent post-Gulf War era, and I suppose the biggest villains in recent Western history would have been Stalin...and Hitler, who I believe gets name-dropped in the revised draft. It's a clever way to steer the audience's emotions against Koopa by contextualizing his dictatorship in something most Westerners recognize as evil.
But seriously, so far this has been a great experience--and there will be more! And be sure to check out the SMB The Movie Archive site (linked above); they've got some really neat artifacts over there! Even if the Super Mario Bros. movie's not up your alley, you may end up seeing it from a new perspective. That's exactly what happened to me.
