Dragon Wars - D-Warthis is an excellent film! Our main characters try to escape from a beast that will never stop. There is so much action and destruction that you just cannot take it all in, even in slow motion. If you don't have a blue-ray player, buy one now and blow your friends away with this movie. I should've given it five stars -- I know you will.
