Lorca is far and away the best character in the show. Sort of like if somebody took Commodore Decker, Gowron and Gul Dukat and threw them in a blender. Cold blooded, crazy and broken, yet gets results and sees the big picture of the war far more clearly than the typical warm and fuzzy Star Fleet types. Plus, his character's ****-what-everybody-else-thinks attitude makes the whole Burnham redemption angle work.
If you haven't seen last night's episode yet
Love it.
