So far, Stardust has been the best. It reaffirmed to me how much I love fairy tales, even more than 'traditional' fantasy. I think maybe it's just because the analogy of the hero's obstacles representing his own internal struggles is so very thin, that there's just something deeply satisfying and resonant about it all. I just love the juxtapostion of a world where anything at all, no matter how fantastic, can happen with the core plot of loyalty, love, emotional maturity, and tough choices.
Plus, the movie had flying ships, walking stars, witches and stuff, and that's pretty cool.
Other recent MWMSOSFOAIAF include Eragon and My Super-Ex Girlfriend. Okay, so we knew My Super-Ex Girlfriend would probably be bad, and it was. But any movie featuring a shark thrown at high velocity into a high-rise apartment is okay in my book. And Eragon was better than I thought it would be, though still pretty cheesy. Casting John Malkovich as the arch-villain probably seemed like a stroke of genius, but in practice it was just sad and wrong. And the costume designer should be run out of town on a rail.
