I haven't watched the episode yet but have seen the OP and ED! I liked the OP sequence, it made me cheer for the return of the show, not sure about the ED yet though. I've watched up to episode 127 or so of S1 so I guess I'll be paralleling with Gintama 2011, I'm very excited to watch it this weekend
Whatever arc they're starting with looks great from the posts in this thread so far!
Also happy about the new dimensions of the show
I agree about the subforum thing too... except I feel like a lot less people outside of Japan watch Gintama than they should D:
