It has a way better story progression and main characters, even going beyond the fact that it doesn't work with the same episodic structure as the first season. There's actual progress all throughout the season, the characters actually make an impact before they receive their own detailed story arc, and I felt compelled to keep watching because I was actually interested in how the plot was going to progress.
On the downside, unlike the first season it has an actual story to tell and could thus have used those 25 episodes instead of being crammed into 12. Aside the main characters no character received remotely enough love, and there were too many side characters to begin with for such a short series. A number of very plot relevant characters were barely shown for a few minutes before being murdered to get rid of them in time. Even the main characters didn't get a satisfying finish, as the ending of it was an incomplete mess of bull****, and there was no time for an actual plot to develop in the first place.
Still liked it better than the first season though, having watched them back to back. The characterization and pacing were just so much stronger despitehow blatantly rushed it was, making me actually interested in finishing the damn thing with its many flaws, unlike the first season that I only felt compelled to watch all the way through due to boredom despite it's general high quality.
