The worst things about carousels that I find are when 1) it's not obviously a carousel and 2) when it auto-advances on a fixed timeout, and it's impossible to stay on one 'page' and actually read it. Extremely frustrating.
Metacritics seems to be perfectly timed to always advance exactly as I'm clicking on an item, leading to it navigating to something different entirely. Always meant to look if there's some troll code in there.
