Just a few questions......
If the riverboat is nuclear powered why is smoke coming out the smokestack? To fool people? There was no wood or coal on board so what was making smoke?
The shoulder fired WOODEN barreled rocket launcher was amazingly accurate and effective. Did THAT have alien technology also?
And If Burton had it why didn't he use it against the boat when it first appeared?
If the airship is also nuclear powered and the ship needed no gasoline why did the engine catch fire? It should have been steam powered like the boat. Was the airship fusion engine making gasoline?
I could overlook the (non)Japanese chick with the (non)Japanese accent since she was hot, could kinda swordfight and had advanced blacksmithing skills.
I wanted to like this movie but the plot had more holes than a chunk of swiss cheese.
