'The Sea Beast' features incredible animation, and some of the most realistic animated characters (humans) I've ever seen - with regards to appearance and proportion. Jacob is also a rather sexy animated creation, mind you!
Speaking of Jacob, he is one of the film's protagonists. As a youngster, he was rescued by Captain Crow and has been living with him ever since. They are monster hunters. Fresh on the trail of the elusive Red Bluster, Captain Crow abandons the mission (against his will) to save a ship under attack by a sea monster.
The Royals pay Captain Crow to hunt sea monsters, but when he fails to capture the Red Bluster on his latest mission, they inform him they will no longer pay for hunters. Instead, they built their own ship, and the King challenges Captain Crow to see who would be the first to capture the Red Bluster.
An orphan, Maisie, who's parents were killed by a sea monster, stows away on Captain Crow's ship and join them on their adventure. The film's first half was mature, with action, adventure and even suspense all the way. It had an incredible sense of realism until that defining moment (almost exactly at the halfway mark) when it suddenly reduced the film to a 'cute' kid's adventure.
After that 'Pinocchio' moment (yeah, you'll recognize it when you see it!), the characters suddenly resorted to silly actions typical of animated films aimed at a younger demographic, and the suspense made way for humour (even slapstick). The believability was completely gone with the feared Red Bluster now being 'adorable'. The film even had a 'How to train your Dragon' character, Blue, acting almost exactly as Toothless.
The film nevertheless remained exciting (although not as much as the first half), and it certainly was entertaining.
