I'm with CiaranHaggerty in that it has yet to be made, and may not be made at all, sadly, but....
With those four as the choices, it's really hard to say for me. I guess Finding Neverland, though, because even though it's not technically a Peter Pan film, we get to see part of the authentic play as J. M. Barrie wrote it--rather than the derivative musicals so often seen nowadays. So ironically, even with the inconsistencies of the historical "story behind the story," that's probably the closest they've gotten to Barrie's vision in a movie so far, and I fear it may be as close as they ever come, at least in the near future.
The Disney version is hard to get out of my head since it's my first experience with Peter Pan (and I've almost got it memorized now), although frankly I don't really care for it that much, and not just because of the inconsistencies with Barrie (even as a kid it didn't impress me as much as other Disney fare, and there was too much physical humor), and now I note the similarities with their version of Mary Poppins, which kind of bothers me--and also their "all just a dream" ambiguity such as is found in the film version of The Wizard of Oz (but not the book).
Didn't really like the 2003 version a whole lot either, though in some ways it was better than the Disney version (like more faithful to Barrie). In other ways, though, it seemed worse: too much CGI special effects, for example, and worst of all, it gives the impression of needing to have a passing familiarity with the story before you watch it (NEVER a good idea in a film), as some things aren't fleshed out (like the Lost Boys). At least Disney's version didn't feel like that (even though we still never knew the Lost Boys' names). Plus I never cared for Aunt Millicent and would have preferred seeing Liza instead (for once)....
As for Hook, I'm kind of in two minds about that. I recently saw it again on TV and this time noted all the references to J. M. Barrie's original, and the Great Ormond Street Hospital, and all the things I didn't get when I first saw the film. While I liked that, as far as it went, the very premise of the film goes completely contrary to Barrie's point, so quite frankly that was probably a BAD idea for this kind of film, to make so many references to Barrie's original. In addition, I felt it was poorly named, as the movie seemed less about Hook himself than about Peter Banning--it's really just a typical "father being reunited with his family and his past" type story (not an un-Disney-ish notion), only in this case the father is Peter Pan all grown up and needing to remember his past to defeat his old nemesis and save his children. I guess I find the premise interesting, but I think it could have been handled better.
I also agree with Hannah High in that I prefer The Lost Boys to Finding Neverland, but aside from it not being listed in the first post, I didn't bring it up because you see so little of Peter Pan itself in The Lost Boys (though I did like the special performance for Michael in the second part of the miniseries). Thus it really counts even less as a PETER PAN film than Finding Neverland does.
