The second season of SnS sucked.
I'm sorry but if you liked this you must be one of the popular girls at your middle school. The first half of this season has absolutely no real action and is complete drama. Now, something you have to understand is that I hate drama, and this got so bad, I read basic synopsis on all the episodes from 6-16 where the spoilers final died and was done. The ending to this season is also kind of a WTF and in my personal opinion should have ended there.
I wouldn't really waste my time with this season and just watch the first one and then ask a friend whose seen the anime or just look up a video bit of the ending, which, by the way, was really slapdash work.
