Mistakes
When Andromeda and Perseus wake up on the beach, Andromeda tells Perseus that Argos needs a new leader/king. The problem with this is there is nothing onscreen to show that she even knew her father the King had died. She was hanging by her arms facing the Kraken and she couldn't turn around. By the time her father died, she was already falling into the sea, so again, she shouldn't even know her father has died. See more...
