Anybody who has worked "a" game, has made mistakes. The question was about "leeway", not about constructive criticism. There is a line, somewhere, bewteen constructive criticism, leeway and nitpicking something way past death.
Perhaps someday we'll have the technology so everyone watching a game can instantly vote on whether the 285th camera shot proves something happended, or didn't happen, by a pubic hair, but I wonder if there will be anyone interested enough in the game left to care. I frequently try and remind myself, "opinions are like IDIOTS, everyone has one, and it's just a little different than anyone elses".
