I just watched the first 4 episodes of SPN and I can see why some feminists have road rage over it, but I am def intrigued. Well, I didn't watch Wendigo only 'cos I watched the ending of it ages and ages ago, back when the premise of the show just made me eyeroll. "They probably won't represent the monsters correctly," I thought, and apparently I am right(?) but not in the way I thought I'd be.

From reading the comments in this post, I concur with almostinstinct that the bookverse and movieverse splinter groups are essentially interpreting different texts. Movieverse actually touches on how difficult it is to adjust back to England after 15 years in Narnia, so it's less of a leap from there than from bookverse. The themes are different.
