Losing Gollum's Soul

[The Saucepan Man]

He's chosen rather to send people coming out of the cinema saying "I don't like/ I hate how Frodo turned on Sam".

I think people (at least those who have not read the book) will be more prepared to accept Frodo's reaction, resulting as it does from a combination of Gollum's machinations and the increasing hold which the Ring has over him.

Have Sam try to apologize to Gollum after losing the fleeting shot at Gollum's conversion

The you lose the tragedy, and the point of the scene.
