Even liberal critics are criticizing Clooney's character (not so different from real life character) over Global warming. How can it possibly be subtle then, as some have suggested. It's tanking at the box office. For those who saw the movie and loved it, what say you? from the article:
“Clooney seems to have been cast as much for his liberal credentials as for his star power, and it’s a choice that can’t help but leave a somewhat smug aftertaste,” writes Variety film critic Justin Chang. “He’s almost too fitting a spokesman for a movie that urges humanity to end all wars, take responsibility for the environment, and foster a greater, more alert engagement with the world around us.”
and THAT's the point
