The truth is, the storyline/plot is very weak, quite weak, not very innovative, and has been done before. I also found that the blatant "worship" that Robin has for Amon (especially noted in each opening), is really quite, uncomfortable, almost too slickly made, and appears to be something right out of a Teenybopper video. Now, with these things in mind, would I purchase the next Witch Hunter Robin dvd? Most likely. Here are a few reasons why I would:
First of all, it's an easy anime to watch. It doesn't really make you think all that much, but it's got a dark, mysterious atmosphere to it that's interesting, and Robin, although her dubbed voice is not to my liking at all (she sounds very weak and easily taken advantage of), is a very interesting character. She is undoubtedly, a very interesting character, which makes me wonder what she sees in the conventionally handsome, but dull, Amon.
All in all, plot is a bit redudant, but then again, most anime rehack the same stuff over and over again. Despite its faults, I can't say I wouldn't recommend it, and I am actually curious to see what develops for Witch Hunter Robin, because she is the most appealing character in the anime as of yet.
