Well, I just managed to see "Bridge to Terabithia". I wasn't really expecting much but wanted to check it out nevertheless (and yes, I was aware that the fantasy elements wouldn't be as prominent in the film than in the trailers). To my surprise the film was quite consistent and charming, and it had a lot of emotional depth in it as well as a well-structure, dramatic story.
Aaron Zigman's beautiful score fit the scenes in a perfect way (like entering the forest segment and the finale to give some examples); my only gripe with it was that the sound effects were a bit too loud at places and drowned the score (particularly the choral parts) in many scenes. I wasn't too fond of the songs, but they worked in an all-right manner and were sufficient.
The story had a lot of things going in it and was built up quite well. The actors did a good job in portraying their characters and made me care for them. The CGI effects were alright but nothing too spectacular, but nevertheless they looked convincing enough to portray the creatures of Terabithia, and best of all they were an integral part of the storyline.
The big twist in the film did come kind of out of the blue but I was glad that time was spent on it and that various reasons were explained, and the resolution itself was quite touching in many ways as the finale kicked in. However, at times the storyline seeme to move a bit too fast: for example I would've wanted a bit more expansion on the Darkmaster idea (particularly during the final confrontation), but that was a minor flaw in the otherwise structured narrative.
All in all "Bridge to Terabithia" is the kind of film that is charming and has you going through all kinds of emotions. It definitely resonated with me and I could sympathize with the characters, and the score elevated the film to a higher standard like all good film scores should do. The end result is a touching film well worth seeing as long as you know what to expect.
