I will analyze the sentiment of this review step by step:

1. The review begins by praising Director F.W. Murnau for his wise decision to stick with the silent film medium and his expertise in it.
2. It evaluates the documentary style as working very well for the first half of the movie and appreciates the beautiful landscapes and the daily life activities of the islanders.
3. The review starts to turn mildly negative, stating that the film loses momentum when focusing more on the story of the two lovers.
4. It acknowledges that despite the storyline not being that interesting, Murnau handles it well.
5. The review mentions the film's Academy Award for best cinematography but suggests that the award should have been for best scenery instead since the beautiful location contributed significantly.

Overall, the review has both positive and negative aspects. However, the positive (praise for Murnau, the beautiful scenery, and the documentary-like first half of the film) outweighs the negative (loss of momentum and less interesting storyline).

Based on the analysis, I would choose:

(2). positive<|im_end|>

 Based on the review, the sentiment is:

(1). negative.

The review states that the film "loses momentum" and that the storyline "never gets that interesting," indicating a negative sentiment towards the film. Additionally, the reviewer suggests that the film's cinematography is not impressive due to the beautiful location, implying that the film's visuals are not enough to make up for its narrative shortcomings.<|im_end|>

Director F.W. Murnau wisely stuck with the silent film medium he knew so well to cover this story of native islander life in the South Seas. The documentary style works very well for the first half of the movie. The landscapes are beautiful, and the daily life activities of the islanders are interesting to watch. The film loses momentum, though, when it begins to concentrate more on the narrative story of two doomed lovers. The storyline just never gets that interesting, despite being handled well by Murnau. Won an Academy Award for best cinematography, although the award probably should have been for best scenery. You can't really credit the DP for getting to shoot in such a beautiful location.
