When you click on Pan's Labyrinth in the master list it brings up Master and commander instead.

I'll report back if I find any more errant links.

EDIT: Actually every single link in the list pre-intermission is shifted by one. And anything after the intermissions start either links to a random commentary or simply pulls up a page with the text but no images, that also cause the rest of the page to freeze.

Also, trying to scroll through the menu basically breaks it, and I end up either snapping back to where I was, or the entire thing just turns black.

EDIT to the Edit: And now it's fixed. Well wtf. Should not have taken another hit, man. Holy crap.

Your browser is just caching the JS files. I fixed a bunch of site bugs earlier, and so some of the files might be out of date. Spam CTRL+F5 like a dozen times and it should update.
