- Dune, done properly. The David Lynch version looked the part (mostly), but failed in the script department, whereas the SciFi channel version got the script mostly right, but suffered from horrible set/costume design and acting.
- Also The Dark Tower done properly. I know they're making it now, but they're condensing 7 books into 3 movies, a 6-episode miniseries, and a single-season TV series (which is likely to be the entirety of the Wizard and Glass flashbacks), both on NBC, which makes me very concerned for the quality of the final product.
My biggest fear, other than stuff getting cut (though I honestly wouldn't mind a dramatic re-arranging/re-structuring/re-write of the last 3 books for the film versions - maybe 5 or 6 films would be enough), is the watering down of the material. The fact that the TV projects will air on a US network worries me, but I'll be furious if the film(s) end up with a PG-13 rating.
- Finally, His Dark Materials, re-done from scratch (which kinda sucks since the first adaptation of The Golden Compass had a great cast), with almost anyone other than the director of American Pie at the helm.
