Murder Company is a very basic, moderately watchable, WWII action flick.
In spite of the presence of Kelsey Grammer, this is very much "B grade" material. The bare bones story offers little lead in or resolution. The narrative and characterisations follow the same, simple trajectory.
That's not to say its not watchable. Taken for what it is, its a fun, exposition driven action romp, that mostly, gets it right (not sure why German ammo crates would have English written on them?...oh well...).
In summary, Murder Company is a B grade WWII action flick. Its not dreadful just don't expect any Saving Private Ryan moments and you'll be fine. One for a slow afternoon or evening.
