Just thought I'd bump this one up again to see if anyone's picks or lists have changed. Honestly, I don't know if much has changed for me, as I seem to keep coming back to the same movies or franchises. My list doesn't get too varied I guess, and there are a lot of other movies I like, but I seem to keep coming back to the same list:
1. Star Wars OT (any really, although Empire is a personal favorite. ANH is best "stand alone")
2. The Lord of the Rings (again, any, but I've always liked Fellowship a lot)
3. Indiana Jones (Raiders)
4. Spider-Man 2
5. Harry Potter (like them all, but have always really liked Prisoner of Azkaban)
I started rewatching the LOTR EE this week, just getting psyched for the Hobbit, and those movies are just so strong start to finish. The Spidey movies are special to me just because the character was a big part of my childhood (and adulthood I guess) since I was 5. I've enjoyed a lot of the comic movies lately (Cap, IM, Thor, Batman, X-Men, Scott Pilgrim, etc.), and really liked the Muppets last year as well. Aside from that I usually end up back at the old classics like the Goonies, Ghostbusters, ET, Karate Kid, etc. I could probably almost make a "classic" and "modern" list as well.
