I recently got two second hand comics, one of them being Fire & Honour, which narrates the adventures of the Cadian 71st Imperial Guard company fighting against the Tau in a planet where the Governor is a traitor (allied with the Tau).
The drawings are quite nice, very well colored and vibrant (despite depicting scenes of war and battle). Here what fails is not the drawing skills but the writing skills. The texts are typical hard-ass soldier speeches, cocky comments and drill sargeant orders, all around a weak, plain and obvious story which doesn't even tries to make itself interesting.
Nice for reading once but much better to grab a Black Library book if you want a good plot.
