I was going over New 52 Superman's tenure in the flagship books (Action & Superman), and I realized that there were actually more issues that I considered to be good than bad. It's in the positive just barely, but until now, I had thought there were a lot more issues I considered to be bad than good, probably because writers like Lobdell were stuck on my mind.
For the rest of you, do you prefer New 52 Superman just because of Morrison's run and/or Pak's run? I'm speaking strictly about what you thought of the quality of stories from the flagship books, so the potential you saw in New 52 Superman is not really a point of discussion here, nor is his relationship with Wonder Woman and Batman outside of the two flagship books.

Some of the bad issues weren't so bad as they were mediocre, but they certainly didn't rise to the level of good. In the case of Superman #52, it just barely passes as good.
