Just came back here to see if any parents took their 2 - 5 year old children, and I most certainly see a stack of them..
PG, MA+15, PG+13, M ratings are not even suitable for children, yet you choose to take your 5 year olds to this movie. Of course they're gonna cry, because you're forcing them to see the movie.
There's the trailer for a reason! Watch it instead of being somebody who would take a baby to see "The Nun II" or "Smile". That's bad parenting on you, you should be more alert on the ratings, so just keep quiet, and learn your mistake.
When I watched this before, I got shocked at the amount of 5 year olds watching this movie and 'crying'. Although imo, this movie is very cool.
