给你找个定义吧: A B movie is a low-budget commercial motion picture that is not definitively an arthouse or pornographic film. In its original usage, during the Golden Age of Hollywood, the term more precisely identified a film intended for distribution as the less-publicized, bottom half of a double feature. Although the U.S. production of movies intended as second features largely ceased by the end of the 1950s, the term B movie continued to be used in the broader sense it maintains today. In its post–Golden Age usage, there is ambiguity on both sides of the definition: on the one hand, many B movies display a high degree of craft and aesthetic ingenuity; on the other, the primary interest of many inexpensive exploitation films is prurient. In some cases, both may be true.
A little bit shy to say, last night I watched both <> 1 and 2, 2 is not as good as 1 is. :) For me, it is fine, I just wanna find movies can attract my attention to watch from the beginning to end. I got used to watch 60 TV channels in 1 minute. :)
