G.I. Joe: Retaliation is yet another mindless action movie in which the plot cannot be taken seriously.  There is a really awesome action scene which involves a bunch of bad ninjas against the two good ninjas while rock climbing.  Other than that, I think the predecessor movie (2009) is slightly more creative.  In terms of continuity I’m disappointed with the treatment of three important characters from the first movie: one dies early, one only makes an appearance then is absent for absolutely no good reason, one is completely ignored as if never existed.
