Well its not that bad come on, a cross of 'Star Wars', 'Godzilla', 'king kong', 'Jurassic Park' and all other monster flicks ever hehe. The effects are alright, very good for Korea but less so for Hollywood, but they still look fairly good, the only real problem is when people are bluescreened against the action, then its obvious.
The plot, like allot of Eastern movies, its confusing, with lots of odd names, sorcerers, magic and creatures running around, you lose it big time.
The acting is slightly below average but you can live with it, the main claim to fame here is an awesome monster battle between US soldiers, dragons and all manner of warriors with weird weapons, including a pretty good 'Star Wars' style Apache choppers vs flying dragons through a skyscraper trenches section, probably the best part. On the whole I quite liked it, its fun stuff and actually beats 'Reign of Fire' thats for sure.
