Opinions on the changes to Sam and Frodos relationship.

when i first heard frodo say, "go home, sam" i was soo angry because i too, am a huge fan of frodo and sam's relationship; sam would never leave frodo, etc. however, after seeing it the second time, i wondered how they would get frodo and sam separated dramatically enough for sam to find frodo in shelob's lair if they hadnt had sam leave frodo...in the book, sam just gets lost (i think..); which is fine for the book...but for the movie, since it's such a dramatic part, i can completely understand why it was added. and it makes you wanna slug gollum really hard......
