Yeah, it certainly isn't for everyone. I've known of people who liked the slice of life sections of the comic but groaned at the video game elements--which the movie seems to be selling itself on pretty hard.
OT:I started the previous thread for this! I have to see it.
I was a little underwhelmed by the final volume of the comic(Actually from volume 3 until the final showdown had me gripped; it was the final fight that felt a little "meh" to me), but it was a good end.
I'll be interested to see the difference in the movie's version.
