The 2 previous reviewers obviously don't get the aim of these Live Action episodes for Tom Clancy's The Division: Agent Origins, a video game made by Ubisoft Massive.
The characters in these episodes are not represented in the game, they are based on hypothetical back stories for characters that 'could' exist in the game universe. The game is highly customisable and you play the game as a protagonist that you create. There are set characters within The Division game universe but none which are seen in any of these Agent Origins episodes.
To add to that these are promotional story trailers for a video game. I repeat - a video game. They are not part of a main feature length movie. So besides already spending thousands if not millions of dollars on already actually making the game, Ubisoft has a marketing/promotional department who probably have a finite amounted budget to use on promotional material such as back story trailers/episodes. If you have actually followed the game's development there has been a vast wealth of promotional videos covering various aspects of the game's features, development, story, community events.
Back to the Agent Origins short film, there most likely never would be too much fleshing out of characters, a huge production budget or development of a feature length story - that's what the game is for.
If you're a fan of the game you most likely have already seen the Agent Origins shirt film/episodes, and appreciate the production, mini-stories, characters, gadgets/gear, weapons, action sequences, easter eggs, and setting that they're shot in.
The Agent Origins live action film series is supposed to be short & sweet, and it hits the nail on the head in regards to The Division's atmosphere, setting, and main game points. The action sequences are exciting to watch with great audio and SFX keeping you in the moment, and the action is not too heavy, with equal snippets of humor, drama, and character and story development thrown in between. There also multiple perspectives shown, such as from the bad guys (Factions), civilians caught in the conflict, and of course the Agents themselves.
If you are a fan of the game, or curious about the game, I would recommend this to you to watch.
I would also recommend watching Ghost Recon Alphas - another short film made by Ubisoft.
