Dude, that's the whole point of the scene! You think they're screwed, and then the solution turns out to be to not fight. It's a totally unexpected anticlimactic ending to the scene. Reepicheep shouting "Don't fight!"

I'm gonna be mad if they end up defeating the serpent through actual fighting. Lewis did something original and creative. Please don't turn it into something cliche!

Yeah they definitely shouldn’t actually fight the Sea Serpent. But Minotaur’s would add some extra strength to the crew.
Although I don’t know if they could push the Sea Serpent very well if their hoofs are slipping all over the deck.
And they have to keep that line from Reepicheep in the movie, that’s one of my favorite quotes in Dawn Treader.

Maybe, I was unclear. In no way do I want a fight to occur. I am simply realizing that some extra strength would be handy.

I honestly feel that a group of men could have little to no affect on the coil of a huge sea serpent, even if they were just pushing it left or right. To try and push it upwards over the stern of the ship. This has actually been one of the things in Narnia that is too fantastic for me to accept.

I do wonder if Lewis concieved of a much smaller serpent than I have.

This is what I hope they do:
I want them to attempt to fight the Sea Serpent, but fail to do anything, as in the book, with Reep shouting not to fight. So, if everyone who watches VDT has seen PC or LWW, they'll most likely remember that minotaurs are strong. If the Sea Serpent is too strong for even the minotaurs to fight, it will bolden the fact that the Sea Serpent is very relentless.
So, keep to the book.

Seems to me everyone's misinterpreting StBrianofMinneapolis, he didn't say the minotaurs should fight the serpent; only that their strength would help push it off. Let's not attack him for merely suggesting what Lewis wrote into the book with the addition of creatures we already know are in the film!!!

However, there may be more of a battle than was in the book, even if we beg them not to have one. Hopefully that battle will end the way the book ends it, though. Of course we do want Eustace to ruin one of Caspian's best swords; that's a classic moment that has to be in the movie. (Interestingly scary thought on that... Peter gave Rhindon to Caspian at the end of PC, right? *gulp* let's hope that's not the one he hands to Eustace... )

I don't want them to fight the sea serpent, but you might be right, it could look kind of silly in a movie to push this giant snake, where it works fine in the book, I think. But with the minotaurs it might look better. As long as they do not defeat it by fighting, I'm happy for now!
