Ah, Gundam Thunderbolt. What can I say? There is a great appeal to this series for its high-quality production: animation and sound. I could even consider this short series to be a music video of the sort. (Have you seen intersella5555?) If you are looking for a complex narrative to attach yourself to, this is not it. Let's delve further, shall we?
Animation: Little needs to be said about the animation. The backgrounds and character designs, I found, are simply gorgeous. Whether its the bleak, war-torn space scenery to the background characters that highlight the atrocities of war.
Sound: As an avid jazz-head, this is what initially attracted me to this series. What shocked me was the various genres in the OST. Country music, free jazz, post-bop, and a melancholy ballad come to mind when reflecting on the music. The sporadic mix of genres put left me off-putting. Nonetheless, I did enjoy the music regardless of this erroneous sun glare.
Characters: The story focuses on the zeon and federation ace pilots: Lo and Daryl. Whether you route for the reckless Lo or give sympathy to Daryl, you'll find that both of these characters are one-dimensional.
Story: If you are looking for a ton of gore and death, look no further! This is some war porn. This show portraits violence for the sake of itself. At a certain point, the countless deaths lose their shock-value. If you are looking for a gripping realism of war, go somewhere else.
In conclusion, the story and characters are supplements to the production. I personally enjoyed this series. However, this is not for everyone.
cheers,
Baba
