I totally agree, maybe 1 in 100 web pages actually NEED any of the code they run. Mostly it's reinventing the wheel. Where a flat site with fixed HTML and pretty CSS would be fine, they add a splash page so they can show a logo, they'll break navigation and reimplement the browser inside the page with JS so you can't use the back button, they'll style everything on the fly when nothing is dynamic, etc. Nonsense.
