With the movie of the series hitting theatres in Japan this is probably not a bad time for me to finally get to the SP.
And on side note I do want to praise the series for knowing what a cracker is and that it is different than a hacker. I cannot recall any other time I have seen a series make this distinction so it gets kudos from me for it.
If you liked the series you will probably like the SP as it is much of the same. You may want to just skip the recaps in the first half though. But it looks like if you want to watch the movie you should at least watch the second half of the SP.
