Everyone is just complaining because of the same sex couple on it. Saying that they're "pushing their sexuality onto our children!!" Yet if it was a straight couple, it wouldn't be a problem, even though it's sexuality. Some "Christians" just find any excuse to be homophobic.
I'll admit that the plot was boring and slow, but people are just giving it bad reviews because of that small moment in the movie. Grow up. Sexuality is sexuality no matter if it's straight, gay, lesbian. Don't be bias. Children already learn about it, you just choose to complain because it's not what is "normal".
They're not pushing anything onto any children, it's a part of life, just as straight relationships are. Don't criticize LGBTQ relationships in fictional movies just because you're homophobic.
