Here's one that I love that seems to get a lot of hate. (not sure if there was a thread for that topic but I couldn't find it via search)
I knew when I saw the trailer for it I would love it, and after I saw it in the theater I was obsessed with it. I think I saw it 7 times when it was released...
Sky Captain and The World of Tomorrow
Great cast including Jude Law, Gwyneth Paltrow, Giovanni Ribisi, and Angelina Jolie. I loved the "steampunk" vibe. The mashup of WW2 era and sci-fi elements. The use of Laurence Olivier archive footage. Just an awesome little retro adventure.
