It's not that old school. The New 52 was full of them, especially during Snyder's time on Batman. Hell, Super Heavy (the last arc with Gordon as Batman) took a year to get through.
Ah, see, I ended up skipping most of the New 52 stuff. I started out with it, but lost interest. I was thinking about back in the day when things like Secret Wars came out and that was once a month for a year.
Although I'm not too crazy about the $5 price, I'll seek out the first few issues to see how they are.
