Youth (a film)

I have just watched the film "Youth".
The only word that comes in to mind is beautiful. The colours are beautiful. The cinematography is beautiful. The music is beautiful. The camerawork is beautiful. And most importantly, the emotion1* is beautiful.
Compared with Paolo Sorrentino's latest film "La grande belleza", this film's structure is more complete and not quite as piecemeal.
This film is a little boring*, but I enjoyed it.
But I don't understand some of the metaphors yet*3.

1* Sounds like you want to specify one emotion. In a film or story you usually have several different emotions. Maybe more usual in plural "the emotions are ..."or more specific "the emotion conveyed is". Alternatively you could use -the feeling, the sentiment 

2* More usual and positive 'a little slow'

3* More usual - "I still don't understand some..." Yet sounds like you are quite sure it is just about to happen. "Still" sounds more like you have to wait.
