Marauders is a pretty typical example of ST: Enterprise. This is no surprise since it hails from the in-house writing team that produced so much of the formulaic stuff from Voyager on-ward. The characters do nothing surprising - sticking within their predefined limits (and therefore failing to develop) and the story, though entirely coherent, doesn't really grab its audience.
Klingons play the role of the heavy in this. The Klingons depicted here are one-dimensional creatures with much less intelligence than those depicted in TOS, TNG and DS9, and are somehow much better understood than they were in the first contact made earlier in the Enterprise series. Another remarkable inconsistency in this episode is the fact that the universal translator appears to be functioning at 100% efficiency and 100% of the time. In fact, it has apparently disappeared - unless the federation has borrowed translator microbes from the crew of Moya on Farscape.
A mining colony populated by undefined aliens - with the sort of minor forehead cosmetics that usually indicates that they are very much like us and also the good guys - is being raided by Klingon marauders and can not fight back. The Enterprise needs some of the material they are mining and can't get enough because of the Klingons. Archer and co to the rescue. Ho hum. Larry Cedar's subtle but excellent performance is the best reason to watch this one.
