I'd prefer up/sideways/down. Sometimes I watch things that are brainless, they aren't thumbs up worthy but they are not totally thumbs down either. But if this was hiring a sideways is always down in my book, so I could see why it's not totally useful.

"Sideways" exists: don't rate it.

Not rating does not mean the same thing as rating something as average.

Not in a literal sense, no. But I bet their model treats it similarly.
