Steven reminded me about this point with the summary: "Reports are that [Kampfer] starts semi-serious but rapidly descends into farce and fan service, and ends with an incomprehensible trainwreck."

At first, I wanted to rise in disagreement, because I thought that he misunderstood how 11+1=12 scheme worked in 08th MS Team and Kampfer. In both cases, the first 11 episodes tell a story and end with an epic climax, and then 12th episode is a holiday extra (in case of 08th it was utter garbage, so much so that I suggest not to watch it at all). But then I remembered that there was a noticeable slippage in the way Kampfer treats its own setting.

The fighting is affected most noticeably. In the first episodes, characters actually put some effort into it, and the viewers are made to think if Akane is a good shot or not. But by ep.11 Natsuru is hit with 3 weapons at once, while in human form, and nothing bad happens to him beyond a light concussion. This is just ludicrous.

So, SDB heard right. I would not say "trainwreck", since the show was a pretty fun romp to the end, and in exchange for realistic fights we received the entrails animals doing the epic thing you need to see. But yes, the tone of the series changes into a farce along the way.

UPDATE: Steven mentioned that Macademi Wasshoi implemented 11+1.
