By my rough count 29 of the top 100 were #1's of some kind (series starts/re-starts, first issues of special event series, or special one-shots), and 100 out of the top 500. One-shots are no big deal, and new series starting are actually a good thing since it's bringing in some new material. But the re-starts of existing series are nerve-wracking. Marvel was the egregious here - in 2014 we got #1's from the following long established character and titles:
- Amazing Spider-Man
- Silver Surfer
- Fantastic Four
- The Punisher
Like I said at the top, number one issues make up a major chunk of the top selling issues. Whether it's a new series or the next chapter in an existing one, a number one issue always gets more attention and often sells well. But if you're a serious collector it flat out sucks. The one argument I'm sympathetic towards when it comes to people bashing the New 52 is that the long running legacy titles (Batman, Superman, Detective Comics, and Action Comics) could and should have been continued with their existing numbering. Every time you start over with a new number one it devalues the previous number ones. For collectors who put real time and effort into putting together a collection of a series it's a real deflater. Unfortunately the only way to put an end to the practice is to stop buying these number ones, and as the sales numbers show that's not going to happen.
