I'm primarily in agreement with Inkspot here --
Dawn Treader was an okay film. I'll keep watching it every now and again and will keep getting some satisfaction from it, regardless of how close it was and wasn't to the book. I'd really need to see both films again to decide whether
Prince Caspian is worse - certainly at the moment I'm thinking that took more away from its respective book with the filmmakers trying to make it more of an action film or whatever.
I don't think it follows quite so sure as you say that a film that doesn't do brilliant at the box office is suddenly a bad film. Lack of advertising and all sorts can affect this and there are examples out there of good films that didn't do so well at the cinemas. (And vice versa that box office high scorers aren't always great films.)
You might not like the film - that's fine, that's your opinion - but if there's people out there who do get something out of it then it must be doing something right for some people, and they're not all going to be less wordly informed children!
As to Douglas, maybe he's not cut out truly as producer material. Also ideas can still change through the line, even if it's the producer's say so. Well I don't know, I don't know him enough to speculate his thinking too much.
I would like to see more film outings for Narnia. Films as
The Silver Chair have a lot of potential, and
The Magician's Nephew I've never seen any adaptation of. I will be hoping they will have learned to follow the idea from the books better. Eitherway I will still watch it.
(Oh yes, and I will say the acting in
Treader isn't brilliant by all. Will was great as Eustace, though. Part of the reason was the awkward script in parts, like Lucy and Gale's cringy moments!)
