There are people debating about whether or not the movie was good enough to warrant her saying "Saying it was the best would be an understatement," as if 1. People did not inherently have different opinions about things because they are different people, and 2. as if saying something was "the best" actually means it was the best. That's just an expression, man. If you get someone to geek out hard enough, they might call multiple different things "the best" in rapid fire. Things that would be in direct competition with each other and thus, they'd have to Highlander each other because "there can be only one" best.
