In terms of movie favorites, I don't have a single top of the list, but I have some that I like for either the best reasons or quirky ones.
The Lord of the Rings trilogy captured Middle-Earth beautifully. Yes, a bunch got left out, but as was mentioned, watching the full trilogy in a single day would leave you exhausted and bleary-eyed. Not only that, not everyone would get the symbolism of Tom Bombadil, who never made it onto the screen at all. In Return of the King, that scene where Aragorn releases the promise-breakers was so exactly like I pictured it from the book that it was like being there in the very pages of the story.
Young Frankenstein is my all-time favorite Mel Brooks movie. It gleefully skewers every installment of the original Frankenstein series from (was it...) Universal's pre-WWII horror library. Another Brooks flick, Blazing Saddles, was fun, but not for movie reasons. I considered it to be over the top more than once. I took my Mom and Dad to see it when it came out. Mom and I laughed at the campfire scene. Dad was horrified so badly that Mom and I laughed even harder the more mortified he got. (I get my sense of humor from Mom, thank goodness.)
I absolutely LOVED Forbidden Planet (1956) with so many stars at the beginnings of their careers that it is just incredible. At least half-a-dozen guys and 1 gal who went on to have excellent acting credits as their talents matured. But conceptually it was a lot of fun, too. Trekkers would also recognize just how much it affected Gene Roddenberry when he later did Star Trek stuff.
My wife and I love to watch True Lies with "the governator" and Jamie Lee Curtis in an INCREDIBLE strip-tease. Who says mature actresses can't look sexy? And for reasons I can't quite fathom, wifey loves Harrier Jets.
I must admit a guilty pleasure in the movie Xanadu because I liked the music and when it came out, I was still single and lusting after Olivia Newton John. But it also has one of the last performances of Gene Kelly. I've always liked him even though you can't say he's one of the greatest actors around.
As for Avatar, I enjoyed it even though it was troubling. It was a work of art, a true labor of love of art for James Cameron. OK, the wildly profitable success doesn't hurt... But then, when you artistically look at human prejudice in any of its forms, you see how ugly it can be. Which is exactly the same reason why I liked the first X-Men movie. They BOTH held up mirrors to humanity to show the seamy side of human arrogance and disdain for the rights of others. It HURT to watch the prejudice and hatred, but it was spot-on.
If we are talking B/W movies, there is no middle ground on this one. Either you love or hate Dr. Strangelove (with its sub-titled name). I loved it. The scene where Slim Pickens takes the ride of a lifetime with the ultimate phallic symbol between his legs is truly priceless.
From the early color movie collections, my favorite Robin Hood of all time was the one with Errol Flynn in the title role. I agree with Mr. Gorilla about the Leslie Howard version of The Scarlet Pimpernel. Two great swashes to buckle.
Silverado - a western with EVERY CLICHE' in the book, a stellar cast, and great action sequences.
Here's one that I like for quirky rather than artistic reasons... Lust in the Dust with Tab Hunter, Divine, Lanie Kazan, and many veteran character actors. I was going through tough times with my terminally ill mother when a friend of mine took me to see this. I thought I was going to pitch head first rolling down the aisle of the theatre, dying laughing. Literally ready to ROTF LMAO PIMP. That funny. Here's the premise for you... a thief steals a bunch of money, hides it, and tattoos half of the treasure map on the butt-cheeks of his two daughters. then he has the ill grace to die. Only someone who had bedded both daughters would be able to know about it. And the daughters were Lanie Kazan and Divine. OMG, I'm laughing again just thinking about it.
Another quirky little pleasure is The Bicentennial Man with Robin Williams. He's funny with a totally dead-pan delivery - and yet it is so deeply touching to see someone strive to be what everyone tells him he cannot be. It is a sci-fi version of "Pygmalion" or Rudy.
One last flick and I'm outta here. Not quirky at all, either. Driving Miss Daisy was so intensely painful at the end because it reminded me of my mother in a nursing home. But the Oscar-winning performance of Jessica Tandy brought me to tears at many points throughout the movie with its portrayal of a woman's declining years, attempting but not always succeeding to remain graceful as age takes its expected yet terrible toll.
