Just didn't know that it was based on a comic book and after I read a few John Carter comics online and then rewatch the film with that in mind. I understood it more.
The Wicker Man (1973)
I guess cause it's so odd and hard to classify. It's mystery horror musical sci-fi fantasy film.
Blade Runner.
I'd watched the directors cut years previous & HATED it.
But it was a movie I'd always heard was amazing, so a couple of years later I actually bought the 30th Anniversary release & watched The Final Cut. Its now in my top 5 favorite movies of all time.
