Watched the three so far. Reasonably entertaining, but doesn't go far enough as either as a comedy or a drama as noted. Third was certainly closer to a coemdy and arguably the best of the three.
Interestingly, they DO pay attention to military doctrine when they have to and take the action parts fairly seriously, or at least try to. This is not a Zucker-Abrams kind of military parody. When a character has an IED go off next to him, the others in the team react in apparently genuine tactics, going to defensive positions and calling in the explosion right away. Even afterwards when the character is confirmed alive, one of the others looks away from his position and another one smacks him on the head, to get him back on lookout. I found that very interesting to see in this sort of show.
That, and for some reason I can only think of a slightly tamer Ace Rimmer when watching the male lead. Am I right?
