I wasn't sure how much I was going to like this movie, from the trailers anyway. But I was pleasntly suprised at how creative the story was and especially the the way the story was told. The visual effects were excellent and were not overbearing, like some other movies.
Freddie Highmore was excellent as playing twins, he did not seem overwhelmed by playing to different parts, and brought out differnt nuances to both characters. The rest of the cast was very good, but the voice actors were what made the movie for me, from Thimbletack to Hogsqueal. Absolutley superb.
Over all I thought this was a excellent family movie that will keep any family entertained from titles to credits. And after this movie I want a Griffin as a pet.
