That was very emotional, and it added a lot to the fact that Edmund and Lucy wouldn't be coming back. I liked it.

I liked it too. That is an example of the kind of change that is okay with me. It stayed true to the idea of Lucy and Edmund not being able to go back. It added to the mystery of the painting. Do other things sometimes appear and disappear in it? And when they do is it a doorway to a different world than Narnia?

I liked it very much. It shows that they were making it back to Narnia.

The only thing that would have made it better is to show Caspian and Lilliandil waving at the kids

I thought it was a nice touch....did not mind it at all!

I liked it a lot. The end of the film, though brief, was beautiful. The only thing I think they should have left out was Eustace's narration. The "with all my heart" line seemed a bit forced. The scene would have really had more impact if nobody had spoken (except keeping Mrs. Scrubb's distant voice). With silence from all of them, and Eustace's hanging up the painting, it would have been truly powerful. As it stands, it's the only part of the film that makes me tear up ---and that's saying something.

Although, I'm the kind of person who tears up whilst watching the celebration scene at the end of The Return of the Jedi. But I can't choose my cying films-- they choose me

It was one those things that didn't really bug me about this film. And Maybe, if this movie was a little bit longer like say 30 minutes or so longer I could have gotten invovled in this movie and it would be a really emotional element.

I thought it was a good addition; sort of a gentle reminder that they won't be coming back that way, and for the Pevensies, not at all. Eustace's almost reverence as he puts it up was wonderful.

It also brings up the interesting question, when did the ship appear in the first place? Edmund and Lucy had been at Eustace's house for a good while (267 days?), and yet somehow hadn't seen it. I also find it curious that Edmund says "Have you seen this ship before. [emphasis added]" It must have been there at least for a little, since Lucy says she has. Does the ship appear and disappear at (Aslan's) will? Will the ship ever reappear? Will Aunt Alberta be mortified that her, albeit hated, wedding present has been altered?

I thought it was a cute addition, I liked it, I thought it was very sweet, how when Lucy closes the door to the room and takes one last look at the painting and the Dawn Treader dissappears, I was already crying my eyes out the and this just set a new set of tears (I know I'm an emotional person )

that was pure genius. and also really sad. I cried so hard when I saw that! I was already crying, but that was the crowning moment in my sobbing. I bawled!

I liked it too, it's interesting someone brought it up, a change from the book that was actually very complimentary to the movie (in fact I was very satisfied with the entire ending scene). It had a bittersweet feel to it and like someone said kind of represents Lucy and Edmond being told they coldn't come back.

I think I might be the first person on this thread to say that I didnt like it. Haha. Personally, it just made me all the more sad in thinking that it is very possible we wont get a Silver Chair adaptation. Everything about that final scene seemed way to somber and way too much like a conclusion to the short franchise.

I must admit I don't think I even noticed the ship disappearing. When does it occur? Is the ship still there when Eustace hangs the painting back on the wall, or does it disappear once Lucy turns to look at it before closing the door? I love the ending scene so much, and the last line is deeply wounding. I think I was too emotionally overwhelmed to notice all the details in that scene.

However, the concept of the ship disappearing sounds like a good one. Not only does it give symbolism of Edmund and Lucy not being able to return as you all mentioned, it also could stand for the fact that that portal into Narnia is closed to everyone--even Eustace. It's a visual way of showing that the next time we get into Narnia, it will be through a different portal.

Thank you for alerting me to this little issue.
Yes, another plot hole. When you change one thing, it has implications for other things. And they kept the "haven't looked at the picture before" in without taking into account the long time they'd already been there - which is well established with them doing chores as a regular thing etc.
Each of us will have to think of our own explanation - maybe Ed hasn't been in Lucy's room much? In the book that's the only place they can take refuge in to be alone and talk about Narnia.

The more I think about it, the more I think Eustace was exaggerating/being sarcastic about the number of days the
Pevensies had spent in his house. The specific complaints about "at least you have your own room" make things seem like Lucy and Edmund had arrived there rather recently.
