There are things you just wouldn't see in a Pixar or Disney movie. For example, one of the main elves has an eyebrow piercing, uncommented on. Even more than that: two of the boy elves kiss... each other. It's progressive.
3-D movies are just expensive. I'm sure like, DVD's and regular Blu-rays, the price will eventually come down. For now, they are very awesome but hardly worth $35 per movie...even if you get 3 or 4 or 5 copies of it. What am I supposed to do with 5 copies of the same movie? One way or another, my kids love it and it's hard to match the smiles on their faces when they watch the movie.
Arthur Christmas is one of the most clever animated flicks around, especially if you enjoy British humor! However, the Walmart exclusive 2 DVD pack was a HUGE disappointment, and would only please Justin Bieber fans, because his Christmas video is on the second DVD. There are few other notable features on the bonus DVD, so save your money and buy the single pack.
