I personally find those who say "it made a lot of money, get over it" to be more annoying than someone who makes what I feel to be a thoughtful (albet emotional) dissertation of why a movie sucks.
If you want to defend a movie, please try to use some other criteria besides box office receipts. We all know plenty of good movies fail at the box office and plenty of bad movies make money. It's boring to use the "it made money" excuse.
I would argue that the demographic that liked JJ Trek is probably the least capable of defending the movie based on its intrinsic merits and most likely to reach for the "it made a lot of money" excuse.
