In Bakemonogatari episode 13, Mayoi refers to enigmatic silent character Shinobu as the girl with goggles on her helmet. That got me thinking that it's generally accepted anime characters will have some defining quirk that prevents them from looking like every other anime character. E.g, Haruhi's hair band keeps her from looking like some random K-On! retard. How often does this occur in real life? Is there an article of clothing or piece of haberdashery that defines me? I suppose if I had to pick something, it would have to be either my houndstooth flannel shirt or my combat boots. I do have a rugby shirt exactly like the ones worn by that guy in Rizelmine, but I never wear it. [Update: Turns out I also have a rugby shirt exactly like the one in Summer Wars.]
This apostle of Haruhi fell victim to temptation and watched the horrible cam rip of Suzumiya Haruhi no Shoushitsu. The camrip is strictly amateurish, and of such poor quality the best thing I can say about it is it must be a labor of love. I guess it's still better than the Rebuild of Evangelion 2.0 camrip which I had to close after 10 seconds for being almost literally unwatchable.
As for the movie itself, it's stunning. The comparison is apples to oranges, but I liked it better than both Summer Wars and Rebuild of Evangelion 1.11. Despite its focus on drama instead of comedy, The Disappearance of Haruhi Suzumiya is heavy on the factors that made the original series so good.
Likewise, the movie does wonders for Haruhi herself. [Spoilers: She's in the movie.] Kyon's happiness at seeing her again is our happiness. So too seeing the Haruhi we know emerge from the Shoushitsu Haruhi we meet at first. Gone is the exasperating and vicious Haruhi from The Sighs of Haruhi Suzumiya. We had to lose Haruhi to find her. (Cruel is one thing, but vicious is another—I can dig cruelty when it's packaged with enough charisma.)
Speaking of The Sighs of Haruhi Suzumiya, the second season broadcasts do matter. Specifically, the tanabata episode and "Endless Eight" matter. Without delving further into spoiler territory, the viewer will appreciate a critical aspect of The Disappearance of Haruhi Suzumiya more if he suffered through all of "Endless Eight." Don't worry, it also works if you actually enjoyed "Endless Eight," as I did.
