Like the title said, this short is a pretty good introduction into Sgt. Rock and The Creature Commandos.
I decided to watch this just before watching The Creature Commandos show, and without reading many of the comics, it does a good job at showing Rock's rocky (HA) exterior to his team (not the commandos but his soldier buddies, "The Easy Company").
Although the Creator Commandos don't have much characterising. Besides Sgt. Vincent, the rest don't really speak, and it doesn't help that they only got three monsters for the CREATURE Commandos. Especially wanted more from Frank, but I did like how he seemed horrified by seeing the Easy Company being turned into mindless versions of himself, but that's pretty much all he got besides having pretty good fight scenes.
But honestly, all of that is alright because this was just made to "showcase" Rock and The Commandos to hopefully get people to look into them, and I have to say it worked. I should pick up some of their comics when I can.
