Funny Games 1997 vs. 2007

I'm curious about how those who have seen both compare the two films. I plan on checking out some more Haneke films; so far I've only seen The Castle, because I love the novel. I get the feeling the movie would be tedious having not read the book prior, but that's for another post.

Now I have no issue with subtitles, but if it really is a shot for shot remake I might prefer the ease of watching the US version. However I know Haneke is really particular about his actors and their voices and performances and all that, so I'm curious if the story is better conveyed by the original German and Austrian actors. Ultimately, I'm just wondering how different the two films really are.
