Movie Review Data数据集记录的都是原始评论数据,全部为英文,文本内容举例如下:
films adapted from comic books have had plenty of success , whether they're about superheroes ( batman , superman , spawn ) , or geared toward kids ( casper ) or the arthouse crowd ( ghost world ) , but there's never really been a comic book like from hell before . for starters , it was created by alan moore ( and eddie campbell ) , who brought the medium to a whole new level in the mid '80s with a 12-part series called the watchmen . the film , however , is all good . 2 : 00 - r for strong violence/gore , sexuality , language and drug content
