The Man Who Knew Infinity Review

What I liked: Probably the best part of this movie was watching it was a bunch of math majors. They were so excited about every bit of math that appeared. It was moderately disconcerting because I think this may be vaguely reminiscent of how I act when I watch science movies. The reason the math majors were so excited was this movie was the story of one of the most intriguing and possibly one of the greatest modern mathematicians: Srinivasa Ramanujan. He was a relatively uneducated man living in India who remarkably independently developed known theorems and discovered new mathematical theorems. I know virtually nothing about this guy but am assured by long and complicated (and enthusiastic) explanations that he was an continues to be hugely influential on theoretical mathematics. I assure you that theoretical mathematics is a useful thing for stuff like data encryption and GPS and outer space and that it is not equivalent to hypothetical and absurd answers to math questions that are too hard to think about at that moment. I liked that I new Ramanujan's adviser Hardy, of Hardy-Weinberg fame. I liked the way they framed the story in WWI, it seemed very true to life on a college campus where world altering events are swirling all around but in a rather surreal way. I liked the discussions among the faculty, which addressed bias in the academic system without seeming too dramatized. I liked when he tried to go visit the elephant, it was sad but it did a better job for me of conveying emotion than most other scenes in the movie. I liked the way they presented his devotion. I liked the friendship between the two old mathematicians, I thought they were funny. I liked that they made a movie about very complex ideas and told the story of someone who was very influential but mostly unknown (possibly just unknown to me since every person I talk to about the movie says "Oh yeah! Ramanujan! I love his work on math math math math" but I am attributing that wide spread response on non-random sampling and weird friends)

What I didn't: While the story was good, it didn't really ever get me. I didn't get swept up in the excitement of the plot or in the strained character relationships. I had trouble following the math. Not the math that they chose to explain, that was done well, but the MATH. Why was Ramanujan so cool? Yes he was super smart and brave but why does he have a legacy that makes people say "Oh yeah! Ramanujan!" What was it about his ideas that still inspires people to pursue them? That is the framing and context that I felt like the film really needed. They tried once to address it: Ramanujan is talking to his wife, who cannot even read, telling her about how much he loves math. Essentially he rhetorically asks "but why should this matter to you?" and responds "maybe it doesn't but it reflects fundamental universal truth." This response tells us a great deal about the character but very very little about math besides erroneously that math is not important for those of us who are not personal friends of infinity.

Who should watch this? Anyone with a mathematician friend, or who knows of a mathematician who needs a friend.

Would I watch it again? Maybe but there would be lots of pausing and googling if I did.

The Titanic

What I liked: Liked is definitely the wrong word for it but the scenes of the sinking of the Titanic were masterful. They were technologically impressive, apparently remarkably accurate, and emotionally gripping. The variety of ways in which different people dealt with a completely hopeless situation was both touching and thought provoking. Especially beautiful was the string quartet. In isolation from the love story, the sinking of the Titanic is a tragic reminder of the cost of hubris and the necessity of regulating emergency procedures and capacities. It carries similar gravitas as a war film. At the 25th anniversary of the film, I can appreciate how Titanic has impacted movies made later.  What I didn't: So here's the thing. I feel very bad for you if you died in the sinking of the Titanic. I feel less bad for you if you managed to get on a lifeboat on the Titanic and then decided to get off. I question all of your decision making and priorities if you decide to get off a...

Annihilation

  What I liked: I liked the crystal trees and the creepy people plants. The multi colored lichen and flowers were cool too. I liked how disorienting the loss of time and flashbacks were, they did a good job of maintaining the disquiet and suspense. I liked that they remembered that mutation and evolution has no goal, it's just a thing that happens with all kinds of side effects. I liked their little boat trip in giant crocodile infested swamp. I'm not sure if I loved the silver skin suit but I can't deny that it was interesting.  What I didn't: The heroes are all scientists who go on a mission to find out what is going on inside the "shimmer". For being all scientists they don't draw very well on their test one variable at a time training. If nothing has ever come out of the shimmer, try sticking a stick in and see if you can pull it out. Step inside with a harness on so if you don't come back they can try and pull you back. Walk in a little ways and t...

Vengeance

What I liked: The premise is absurd. A complete dumpster fire of a person from New York teams up with a Texan red neck to avenge the death of the sister. ... by making a podcast. If that approach to revenge is not the most terrible revenge plan I'm not sure what is. Oh wait, it's Dracula kidnapping a historian to catalog his personal book collection, but that is off topic. Along they way the character gets wildly out of his depth and does things that are definitely bad plans. Like meet with a cartel leader alone in a shed, drive a Prius, visit a music producer, more than once, and give an off the cuff eulogy. Certainly at the beginning it carries the awkward discomfort of The Office but it quickly expands to explosions and the conviction to a podcast found only among the certain portion of the coffee shop population. I thought they did a good job of picking fun at both the rural Texans and the big city New Yorkers. I think they really nailed the "intellectual" bros in...
