This is a good, but not great, popcorn movie. A quick review:

• Loud, dumb, too long, and boring in spots.
  
• Poorly edited action sequences.
  
• Unappealing characters.
  
• Stereotypical Americans, Europeans, and Africans.
• Bizarre mix of humor, fun, and sadistic cruelty.
• Nice color photography.
• Great opening sequence with a Conferederate Ironclad in a night-time attack.
