Slow living in black and white

My wife and I watched (endured?) the movie Roma, which chronicles the life of a maid living with an upper-middle-class family in Mexico City in the 1970s. It is hard to know what to say. On the one hand, the photography (in black and white) is amazing. It encourages the viewer to slow down and engage with the moment, whether water going down a drain or the pain of betrayal. On the other hand, it is very slow! There is a social justice dimension but this was not as strong as I hoped. There is a certainly a message about how women cannot depend on men!
Perhaps for me, the most interesting thing was learning about the Corpus Christi Massacre; a black operations army group (trained in the USA) killed more than 100 student protesters. This was part of Mexico's "Dirty war".
