There are some great comments and facts here about this gem and I'll try not to repeat them. Alea presents a realistic, fascinating, and believable dramatization of the moral and political quagmire set in the early-Castro era through the POV of an apathetic bourgeois. The story delves into the inner psyche of Sergio, a lonely eccentric and sets out to illustrate its impact during the alienation on every level intertwined by transitioning culture at that time. He gets caught up in a relationship with Elena, their happiness seems perfect.
Alea elaborates this predictable story in which, from the beginning, the idea is built that something does not fully agree with what Sergio think will happen. The narration submerges you in the timeline and slowly seams things together in a brilliant and subtle way. I have always enjoyed this film minute by minute, the upheavals and the disappoints that happens to break the character mentally. The film is shot in semi-documentary style which is one of the highlights as it pushes the narrative with no room for spoon-fed character development. Even with limited emphasis on traditional storytelling the film carries emotional impact with solid acting effort throughout the runtime. Some may look at it from the view of art-house documentary with newsreel footage of the Cuban Revolution dressed up as a political drama, but it is more than that. Also, I will recommend Stefan Uher's The Sun in a Net (1963), Halina Bielinska's Sam posród miasta (1965), Paulo César Saraceni The Dare (1966), The Vampires of Poverty (1977), The Man Who Sleeps (1974) and Ice (1970). If you haven't seen it, I would suggest you do add it in your watch list.
To conclude Memorias del subdesarrollo (1968) is simply a brilliant character analysis, also a cleverly constructed political drama realised in a time where the facts truly are in your face.
