Che
Whilst both parts are pretty good, I enjoyed The Argentine more than Guerrilla, for 3 main reasons:
1 - there was more action in it, especially once they got to Santa Clara.
2 - it was happier, in a way. Guerrilla was always building up to things falling apart, which made everything feel a little flat. You know where the film will end (Che getting shot) and so everything just felt like it was dragging things out before Che dies.
3 - Catalina Sandino Moreno was in The Argentine more, and I fancy the pants off her.
Gomorrah
Have you seen City of God? Did you wish it was slightly less interesting and in Italian, rather than Portuguese? If so, I have a film for you! Gomorrah is alright, it just isn't City of God, and it really wants to be. If you loved City of God, you'll like Gomorrah. If you liked City of God, you'll think Gomorrah is OK. Also; and it may just be me, or it may be the point of the film or whatever, but I couldn't actually tell who was on which side. Except that Maria and Toto were on the same side, eve though Toto's side shot Maria for her son changing sides. Also, I liked Maria and she got shot about 3/4 of the way in, which annoyed me. Especially because the irritating Don Ciro didn't get shot.
Maria Full of Grace
Predictable at times, but it is still pretty good. It took me a while to actually like the main character that I was meant to be empathising with (she comes off as a bit of a brat to start with) but thankfully, there was a secondary character (her friend Blanca) who is more irritating than Maria. Some of the scenes of her 'retrieving' the drugs are stark and slightly disgusting without being tasteless - I thought they managed to convey the lack of dignity of Maria squatting in a bath shitting out pellets of drugs without being crass or pervy enough to show any real detail. Also, the end shot is pretty cool and it left me with a smile on my face so I can't bash it too much for being a touch obvious. Besides, it has Catalina Sandino Moreno in it. Probably my favourite of the four I've seen.
