movie of the year

so chem we are watching this documentary about a whole thought of stuff about chemistry and it keeps going and it never ends and it is really long, but it is a really good documentary. It doesn't seem like a documentary at all it seems like a movie and it is really good and a good learning experinece and a good way of learning it gives alot of information and i really like it which is shocking but i get really into it and i dont know why???????
