Finally got around to watching this. Quite a nice watch. The early battle suffered a little from the ages old anime problem of one side fighting and the other just standing still, getting destroyed, but towards the middle that fortunately corrected itself.
Banager should just set himself a more concrete goal like living ever after happily with the princess instead of agonizing over every little thing. I suppose it's somewhat realistic he's too inexperienced and limited in his views to see the big picture and thus doesn't realise that trying to save every single life isn't necessarily the quickest way to end a whole war. But on the other hand, if that's the only way he can live with himself, then he can't avoid it to some extent. But it's really hampering his progress. Moreover, it's connected to the fact he's always being thrown around from one faction to another and consequently merely used as a tool - which is exactly what he was complaining about in the desert. So, it's definitely something he should do something about.
Will such a boxset even appear with Bandai retreating from the US market? After all, the Japanese anime business model is to sell only a few copies to a very limited and saturated market for outrageous prices. So, does a cheap boxset serve their purposes at all? One reason problem they had with the Western market was that the Japanese ordered their BDs from the USA instead of buying the insanely priced domestic ones.
