The trilogy as a whole is one of my most favorite movies but yes, the first one was by far the best. The Eowyn character ruined the third one IMO especially when she managed to kill the witch-king of Angmar so easily, and then in the end, I saw her standing beside Faramir just like Persian movies in which every woman finds a husband in the end
You can find excellent stuff among them. Watch
Pan's Labyrinth and Big Fish if you haven't yet. Then watch E.T. as a mixture of Fantasy and Science-Fiction. You also can give Blade Runner a try.
I never thought I'd like super-heroic movies but then I loved Nolan's Batmans. Never restrict your taste to such generalizations or else you'd miss on many excellent movies. I'm not saying that everyone has to like those movies but I really have the feeling that some people tend to have their opinions about certain movies/books even before watching/reading them. These prejudgments aside, I bet you'll even be able to discover Harry Potter series' (the books) beauty
