Help!

So I have to write this essay for film class on any Swedish film and I've limited it down to two:

Fanny and Alexander
The Sacrifice

I need to buy the movie I'm gonna write the essay on because I'm going to be studying it for a long amount of time before I actually turn in the essay and I have $35 dollars to spend.

Amazon currently has Fanny and Alexander for $31 and The Sacrifice for $26.

So, which one should I get?
