The two characters are both good-looking. When I watched the trailer the first time, they are cool and the movie is a serious story. My guess, however, was wrong. The movie is a comedy rather than a serious one. There were a lot of scenes which make me funny. I like the scene the best, that they were running away from the toxic gas, and the scene excited me much.
