First half Great, second half is a real bore.
First half about a first mate and it's captain going on an adventure to the heart of the sea. with whales and such that was awesome. And the first half of the film was the most entertaining in my opinion.
The second half is the cliche lonely-in-sea no food stuff. The second half was a real bore, with suffering of the characters and the whale making no sense attacking the crew.
The second half also was kinda cliche.
The ending however I did like. they managed to live again most of the crew that is. And it had a good feeling towards it. I hate ending that end either depressing or are just plain bad.
