Went to see the movie on Friday with the hubby, and we liked it, though clearly it was a kids movie from a kids book (for instance, we were both a bit flabbergasted at both his parents saying they looooved eachother, but then not taking the chance to see eachother when they could, but it makes sense when it's from a kids point of view. What's important is the relationship with the kid to each parent.)
However, there was one big plot hole that stuck out in my head.
What was Persephone doing in the Underworld on the Summer Solstice???
That makes no sense at all! That's right in the middle of the time she would be away from the Underworld!
