The fact of the matter is, Eustace caused a lot more problems than help in the book. He helped hunt, warm them up, and got the tree for the mast. However, he hated even the sight of his dragon body and caused problems for the crew. They couldn't leave without him but couldn't take him with them. Not only was he a problem as a boy, he was an even bigger problem as a dragon. However in the movie, if it wasn't for Eustace being a dragon, the sword never would have been placed at Aslan's table and the green mist wouldn't have been destroyed, although it looked as though Edmund defeated the serpent. Eustace never shows remorse for what he did or being a dragon. He smiles most of the time, especially when Reepicheep basically says, "It's ok, you're a good person".

How do you know that Dark Island would not have been destroyed if Eustace wasn't a dragon? Aslan allowed the Dark Island to be destroyed by undragoning Eustace. If Eustace wasn't a dragon, I'm sure Aslan would have allowed Dark Island to be destroyed in a different way (Perhaps the Albatross would have brought the sword back to Aslan's table. Horrible idea, I know, but you get the point). Without Aslan present at the Dark Island, the crew would have had a small chance of defeating it.

I'm going to quote Aslan here: "We can never know what would've happened..."

The only time dragon-Eustace really smiles is when the crew cheers him on for pulling the ship; he finally has that feeling of being liked by others. Dragon-Eustace is never really happy any other time than that. The campfire scene with Reepicheep is debatable. I saw that more as Eustace being comforted by Reepicheep. It didn't make him downright happy and cheerful. Of course Eustace is sad that he's a dragon and for the things he did; the tears and sniffling at the campfire says a lot.

For the most part I agree with Dr. Kreeft. There were a few moments where he misspoke, and it would have been nice if he had read the book and watched the movie one more time before making the lecture, since a few small statements were inaccurate, but on the whole I think he was spot on.

I do think that each island in the movie did have its own character to it, and thus he could have given more credit to their uniqueness, but I suppose that is a small quibble.

Dragon-Eustace smiled when he pulled the ship?! I must have missed that! I agree though they didn't show enough of Dragon-Eustace being lonely, depressed, or remorseful.

Indeed he did! Go through it a couple of times, and you'll notice that while Eustace is pulling the ship, he looks back at the crew and faintly smiles. The camera angle is a bit odd, but I'm sure you'll pick it up.

Yes, I wish the movie showed a bit more of Dragon-Eustace being depressed too. What we got was good, but some more would have clarified his feelings more.
