Let's discuss the inconsistent logic of this movie:

• The Beast's fortress can move through space, so why does it have to land and teleport to a different location in the planet every day? Why doesnt it just stay in orbit?

• Where did the slayers get their horses?

• If the slayers have these laser spears why didn't they just carry a whole bunch of them to kill all of their enemies since they suck at sword fighting?

• When we see Lyssa's father's castle it seems to be out in the middle of nowhere. Aren't castles located in nearby farms and towns so that they can defend it?

• When the two kings decide to unite there only seems to be about no more than 50 to 60 guards in the entire castle, how could they possibly fight the Beast with that small an army?

• During the fire in water ceremony it seems both the bride and groom can make fire, throw it into water and make fire again??? Does fire work differently in Krull?

• Does the fire and water ceremony only apply to nobles or can only Colwyn and Lyssa do it? Or can every married man in Krull blast fire from their fingertips?

• When the slayers attack the castle (and everyone knows how deadly those laser spears are) why does everyone not take cover?

• Why didnt the guards have any crossbows or bows to use against the slayers? Why wait with your sword drawn standing like an idiot till you get laser speared?

• Is Colwyn the only survivor of the attack? How comes he only gets a slight wound in the shoulder and everyone else ends up dead?

• Ynyr (a stupid name if there ever was one) says Colwyn must get a weapon called the glaive to kill the Beast. Yet the Glaive is the most useless weapon in the entire movie since all it did was kill a few slayers and rip a wall down. Was Ynyr a con man or an idiot?

• Colwyn picks up the Glaive from a pool of hot magma with his bare hands. Is he fireproof? Is everyone in Krull fireproof or is it just Colwyn?

• Why did the Beast bother to kidnap Lyssa? If he didnt want the prophecy of their son to come true then why doesn't he just kill her? What would a giant alien monster want with a human princess anyway? Marry her? Rape her?

• When Ergo first meets the gang he is a fireball who blasts into a nearby pond just a few feet away. How did Ergo know where to find them? Was it all a coincidence?

• The seer claims that the swamp is outside of the beast's power range yet the beast has slayers and a shapeshifter waiting for them and the seer also claims the quicksand is caused by the beast. Isnt quicksand commonly found in swamps? If the beast could control the quicksand why didnt it just sink the entire swamp and be done with it? Why just turn a portion of it into quicksand where everyone else can form a human rope and get themselves out of it?

• Why did the beast send only one shape shifter? Why didnt it send a whole army of them to kill Colwyn's gang?

• When Ynyr starts moving along the spider's web why does it jingle like its made out of wind chimes?

• So the Widow of the Web became a trainer to a giant spider because she killed her own baby. Does this happen to every mother of the planet that kills their own baby?

• How does the widow know where the black fortress will be?

• When the widow gives the old man his sands of time why doesnt he just put it in his pouch so he can live longer?

• When Colwyn's gang try to grab the fire mares why didnt the wild horses use their super speed to get away from Colwyn and his gang? They are wild horses aren't they?

• When Colyn's gang reaches the fortress why did the slayers bother to open their doors to fight them? All they had to do was keep their doors closed and Colwyn would have never gotten in, right?

• When Colwyn's gang got into the fort why didnt the slayers wake up the beast? Why did the beast keep sleeping while his house was being invaded? Wasn't the beast supposed to be able to tell the future? And if he did know the prophecy was going to come true why did he even bother attacking Krull in the first place?

• One hit from the slayer's laser spears is enough to kill anybody except Colwyn (who just got wounded in the beginning) and the cyclops (who seems to be immune to them). What makes those two so special?

• Ergo turns into a tiger. Why are the slayers suddenly (even when armed with their laser spears) afraid of a tiger?

• Why didnt Ergo turn into a fireball (like what he was when they first met him) and burn the slayers to death? Or even a Dragon? Why a tiger?

• If the beast can shoot fireballs from its mouth why is it vulnerable to fire?

-The glaive gets stuck on the beast's stomach. Why didnt Colwyn just retract the blades of the glaive so he didnt need to pry it out?

-So Colwyn uses his marriage ritual to kill the beast, thereby making the quest for the glaive pointless. Why didnt he realize this before? Was Colwyn that dumb not use his flame powers in all the time he was fighting the slayers and what not? What kind of idiot wont use a flamethrower hand that always been there?

• How exactly does Colwyn's son rule the galaxy one day? Are there another known planets besides Krull thats inhabited? How do they get there?

With all these plot inconsistencies its obvious as to why the movie failed. Rumor has it that it was the most expensive film made by Columbia pictures and was a huge flop upon its release. Whats funny is that while they spent millions on sets, costumes and such, it seems they spent only a few cents on a lackluster script.
