They seem pretty similar to me, aside from the bits I mentioned. I'm sure there are book purists out there who despise both adaptations, regardless of how good both of them are.
I'm not a book purist by any means and I haven't seen the swedish version yet, but Finchers...is just, not, good. Not good at all. He changed to much and none of the changes made anything better, in most cases it actually hindered what the story is trying to do, and then then the film decided to completely shift the theme and tone in a direction that makes no gaddamn sense from a storytelling and emotional standpoint.
See my previous posts for specifics (page 5).
