I'm not against Nolan or Nolan being given some of the credit. However, I hate when I see people giving more credit to Nolan than Snyder. I often see comments around the internet with people saying things similar "Nolan has created another masterpiece!" or "In Nolan we trust that this movie will succeed!" Regardless of how much involvement Nolan had, there is no way he did more work than Snyder.
Also, while I'm not against the amount of involvement Nolan has in MOS when it comes to the quality of the film itself, I do sometimes wish he had no involvement at all whenever I go on message boards like these. There are many people that try to claim that Nolan's involvement with MOS is evidence of TDKT and MOS taking place in the same universe or that a Batman reboot with no Nolan involvement whatsoever will automatically not fit in the same universe as MOS as well as TDKT would due to this.
Basically, it is more of a backlash towards the Nolanites than Nolan himself, as Kevin Smith said.
