Probably The Iron Giant, which I went from liking to loving over the years. And Beauty and the Beast at some level was a payoff for liking animation: yes, an animated movie can be good enough to get a Best Picture nomination! So much potential opened up with that movie that still hasn't been nearly fully realized yet (though, as Waking Sleeping Beauty argues, that film happened only mere years after Disney animation almost went away). I haven't seen Beast in ages; I hope it holds up. But The Iron Giant might be my preferred film of the two. And I know it holds up.
Day 23 - Most annoying character
Many, many, many of the people in commercials. Many commercials are MADE to be annoying, and commercials have to paint the people in them so broadly (you're conveying a message in 15, 30, or 60 seconds) that the form encourages annoying characters.
