Childish nonsense

The last part I think is because the director does not really read comic books, but she was the one also wrote the script.

I find the the whole deal of making wishes and renouncing wishes to be very childish. You can't just take your wish back, that's silly. No cursed magic artifact has ever worked that way. This might appeal to kids and good for them, but it's a hard story for me to get invested in.
