I'm one of those people who have actually quite enjoyed this series.  It's had some issues (acting mostly) but Prince Caspian was a highly enjoyable film that managed to pull in a lot more fans.  That being said I've been anxiously waiting for more news on the third film, Voyage of the Dawn Treader. 

After all of the turmoil this film has had (swtiching companies and such) it's truly amazing we're going to be seeing this film at all.  This new trailer is...ok.  I want it to be great, but on the whole I don't think it shows enough to wow anyone.  It's kind of middle of the road.  It's not bad, but it's not great.  Personally I think it's too bright.  One of the things Caspian had going for it was it's darker style and storyline.  Admittedly the Voyage book was a little more light hearted but plenty of bad things happened along the way.

The trailer makes this movie look too cheerful, and more like a family oriented film (much like the first).  I'm not saying it's going to be bad, but I think we're just going to have to see more in order to win us over.
