Green Inferno
Surprisingly good. Tight narration, really harsh gore-parts and it captures the overall pessimism of its role models quite well.
Could have done without the 'humorous' bits, but they were pretty moderate compared to your average 'fun splatter'-flick.
Nymphomaniac Vol. 1
Boring. Felt like some over-long coming of age-flick with a few sex-scenes and autotelic 'formal experiments' thrown in. Plus most of the humorous parts were pretty awful low pun-bullshit.
Melancholie der Engel
It definitely has its flaws (shitty dubbing, some overtly pretentious dialogue, etc), but overall a very rewarding experience.
Interesting image compositions, Fassbinder-like stylizations, great score, unconventional montage and of course lots of demented sickness (scat, bestiality, animal-snuff...).
