Honestly, the first web page that I can think of, off the top of my head, that is a badly made website is brookline.k12.ma.us.
What were they thinking? Information feels scattered around, the top pictures provide no clue of what they represent (until you scroll over them), and the stupid size of the page. It takes a good 10 seconds on decent connections. The other gripe is how image transitions seem...very choppy due to low framerate. At least smooth it out. The biggest mistake would be to use flash, which can run absurdly slow under bad conditions. Frankly, it's still not nearly as bad as Xerox (which takes 40 seconds for it to be ready to use under many connections), and is cluttered beyond cluttered with its pointless popups that you can't close until it's done popping up!
