Good grief, Scott Pilgrim is not some inspired, creative force. It, alongside Juno and that Nick & Norah tripe, is a triumph of marketing and demographic pandering, nothing more than the result of a group of hired think-tanks trying to zero in on one of the most obnoxiously self-aware cultures ever in modern society. (I of course realise it's based on a comic!)
I love your eloquent musings Bob and I know you're not one of the pretentious twats to be found in said movies so the only conclusion I can come up with as to why you don't immediately scorn these films is that you simply aren't as exposed to the levels of 'indie' idiocy that I have been.
Where I am from, Ireland, all the 'hip' clothing shops are sellings vintage tees with comic book characters emblazoned on the front. Of course not 5 years ago people wouldn't be seen dead in such attire but now every trendy idiot brandishes this apparel in a bid to attain 'geek' cred. Surely this must get to you? Maybe it doesn't...
It's similar to that piece on racism you did regarding Resident Evil 5. While some people saw Whitey with a badge shooting at Black people and instantly thought "RACIST!!", others, like myself who grew up in a relatively racism free world just said "No, not necessarily, relax!"
Perhaps you look at a film like Scott Pilgrim and, being somewhat less accustomed to the insidious world of 'indie', merely judge it based on its merits as a film (which I suppose is exactly what you are required to do).
Unfortunately when I look at this film, all I see is the calculated aesthetic, the typical soundtrack, even the premeditated 'indie' fonts used in the opening credits and say to myself "Well, this will go down great with the 14-25yr old, suburban dwelling, caucasian market."
