My take on it, after watching all 11 episodes and waiting more than a month to let my emotions settle down, is that the characters and story are strong. Each episode reveals more and more about the story, and since they are only 11 minutes or so long, you can watch all of them "marathon style", but I would advise you not to do so.
Even though they are only 11 minutes long, each episode changes our assumptions and fills in more of the story. Unless you are very alert, you might not process all of the information which is revealed, and thus, think that you were never told important things.
Whilst not going into the details of the plot or story, it was both tragic and comedic, and if you watch carefully, everything important is revealed.
So, overall, this series looks great, has great characters, a great story, and is well presented. It compacts a lot into the short episodes, and the glamor can easily distract you from the substance, but the substance is there, as well.
In addition, there is nothing quite like it... when you actually watch it with an open mind, I am sure you will come to appreciate it as more than the sum of its parts. Highly recommended.
