I'm sure you mentioned this already but it's the communication of the depth of feeling these characters have for one another. How else could it be communicated? How many soppy closeups could the audience stand? Extending that to its logical conclusion, "Shawshank", as well a is basically about platonic love between heterosexual men. Without the VO to clue us in to exactly what's going on in their heads, would some audience members have misinterpreted the relationship between these men in a way which compromised the movie?
