I hear that movie is pretty exciting .it was --- exciting .i have never seen a better movie .
A not at all B more than C nothing more than D anthing but why

首先区分各个短语的意思：
not at all 一点也不
more than 很,非常,相当.表示程度深.
nothing more than 仅仅,只不过
anything but 根本不.
综合句子意思（我听说那部电影很令人激动.那是相当令人激动的,我从未看过一部比这要好的电影）
所以选B.
