The only thing weak about Denpa Onna is honestly the writing. I keep on watching waiting for
Bakemonogatari levels of awesome dialogue, but it never quite reaches there. Guess Hitoma Iruma is just no NisiOisiN.
The characters are fun though, with the same style of unique personalities that drew me into Bake, so I'll definitely keep on it.
I saw that but I don't know how much I trust this company I've never heard of
Not sure about now, but back in the day Deep Discount was awesome with their 25% off sales. Stocked up on a lot of DVDs back then.

Though I've heard lately they've been bad with their service (slow shipping) and they've started charging sales tax to places like California, so I'm not sure. Nowadays I don't buy much anymore... and everything I want to buy anime-wise has not been released on Blu-Ray yet.
I went into the ending hoping they would think of a solution that I couldn't and surprise me. But it was just kind of what was expected and I found that disappointing.
But the thing I appreciated most about the ending was that it
wasn't exactly a Deus Ex. Once you took a step back, you realized that this was pretty much how it had to resolve, and it set itself up very well in that regard, without pulling any "oh we suddenly came to this solution that could have been realized 10 episodes ago, but then we wouldn't have a show so we had to delay the character's rationalization process until we hit the 12-episode mark."
