Horizon kept my attention for all 3 hours. I was amazed how fast the time went. The kids in the movie were excellent actors. The scenery was exceptional. It felt like our history was coming to life so we can not forget how it all started here. I think seeing it on the big screen was important. I am not sure I would sat through such a long movie if I was home and had other distractions. The montage at the end was exciting. It was better then the reviews out there.
